The left margin displays annotation glyphs that indicate line status, such as breakpoints, the program counter, or build errors.
You can right-click the left margin to display a pop-up menu with a list of commands and options. You can click the left margin of a line to remove a breakpoint. For more information about setting breakpoints and other glyphs used by the debugger, see Chapter 10, "Managing Breakpoints. The following table shows some of the annotation glyphs that can appear in the left margin of the Source Editor. The line contains an error. You can place the mouse pointer over the glyph to display a tooltip with information on the error.
The line contains a method that overrides a method from another class. Place your mouse pointer over the glyph to display a tooltip with name of the overridden method's class. This glyph only applies to Java classes. The line contains a method that implements a method from an interface or an abstract class. Place your mouse pointer over the glyph to display a tooltip with name of the implemented method's class.
The line is bookmarked. You can add or remove a bookmark by pressing Ctrl-Shift-M. The line contains a debugging line breakpoint. You can remove the breakpoint by clicking the glyph. You can set another breakpoint by clicking in the left margin next to the line where you want the breakpoint to appear. The error stripe is the strip to the right of the right scroll bar and contains marks for various things in your file, such as errors, bookmarks, and comments for the To Do list.
The error stripe represents the whole file, not just the lines currently displayed. You can immediately identify whether your file has any errors without having to scroll through the entire file. You can double-click a mark in the error stripe to jump to the line that the mark refers to. The Source Editor status line is beneath the horizontal scroll bar. The first area of the status line shows the current line number and row number in the form line:row.
The text area on the right is used for status messages. Source code displayed in the Source Editor is syntactically colored. For example, all Java keywords are shown in blue and all Java comments in light gray. Guarded blocks of Java code generated by the GUI Builder have a light blue background and cannot be edited. To customize semantic coloring settings for the Java Editor:. The IDE provides several preset coloring schemes, which are called profiles.
You can create new profiles with custom colors and quickly switch between them. Ensure that the new profile is currently selected and choose Java from the Language drop-down list. Select a category and change the font, font color Foreground , background color, and effects for this category. In addition to coloring, the Source Editor highlights similar elements with a particular background color. Thus, you can think of the highlighting feature as an alternative to the Search command, because in combination with error stripes, it gives you a quick overview of where the highlighted places are located within a file.
The IDE highlights usages of the same element, matching braces, method exit points, and exception throwing points. If you place the cursor in an element, such as a field or a variable, all usages of this element are highlighted.
Note that error stripes in the Editor's right margin indicate the usages of this element in the entire source file. Click the error stripe to quickly navigate to the desired usage location. When the Source Editor is in insert mode, the default insertion point is a vertical bar, and text that you type is inserted. In overwrite mode, the default insertion point is a solid block, and text that you type replaces the existing text.
Whenever the insertion point in the Source Editor is located immediately after a brace, bracket, or parenthesis, the matching brace, bracket, or parenthesis is highlighted. You can set options for the source editor in the Options window.
The Editor category in the Options window contains tabs where you can set options for editor features, including code completion, formatting and folding. You can set options for the colors of text and background colors in the Fonts and Colors category.
The IDE includes several fonts and colors settings that are saved as profiles. You can choose to use one of the default settings profiles or create a custom profile that saves your font and color preferences. Click the Editor category and then click a tab to edit the settings for that feature. Select an item in the Category or Highlighting pane and then modify the color or other properties for that element in the right pane of the Options window.
Right-click the project node in the Projects window and choose Properties. Select Use project specific options in the Formatting panel and specify the options. By default, the IDE automatically inserts matching pairs of braces, brackets, and quotes. When you type an opening curly brace and then press Enter, the closing brace is added automatically. For , [ , " , and ' , the editor inserts a matching pair. By default the editor highlights the occurrences of various code symbols and keywords when the insert cursor is located in one of the occurrences.
You can disable the highlighting completely or limit the highlighting to specific elements. How to select types of occurrences to highlight in the editor:. You can disable the highlighting of all types of elements for the specified language by deselecting Mark Occurrences Of Symbol Under Caret.
You can use macros in the source editor that can generate common source code snippets or perform common editor tasks. After you record a macro you can assign a keyboard shortcut to run the macro on the current file. Click the Start Macro Recording icon in the toolbar of the source editor. The new macro will not be saved if you click Cancel in the Editor Macros dialog box. A special macro syntax is used to define these macros.
For example, if you want to clear the current line in the editor from the cursor, your macro definition would be as follows: selection-end-line remove-selection. Whenever you press that key combination, the whole line, from the position of the cursor, will be deleted. NAME property of each action to System. Code Templates are abbreviations that you type into the code and that the editor expands into code blocks.
The templates can include placeholder values. After you expand a code template, you go through the expanded block and replace the placeholder values. The IDE includes default code templates for various languages. You can use the Options window to create, remove and modify code templates. Type in the Expanded Text tab to modify the expanded code that the template produces.
Type in the Description tab to modify the description of the code template. Click OK in the Options window. In a general sense, code completion is very useful when you want to fill in the missing code, look at the options available in the context of your application, and generate blocks of code when needed. The editor analyzes the context and suggests the most relevant keywords. While you are typing, the list of suggestions shortens. The suggestions listed include those imported in your source file and symbols from the java.
The suggestions that are the most relevant for the context of your code are displayed at the top, above the black line in the code completion window. If the "smart" suggestions are not the ones you want to use, press Ctrl-Space again to see a complete list. The editor guesses on the parameters for variables, methods, or fields and displays the suggestions in a pop-up box. For example, when you select a method from the code completion window which has one or more arguments, the Editor highlights the first argument and displays a tooltip suggesting the format for this argument.
To move to the next argument, press the Tab or Enter keys. To fill in the most commonly used prefixes and single suggestions:. Type a name or part of a name for example, System. To invoke the code completion window automatically when you are typing certain characters:. In the code completion window, the following icons are used to distinguish different members of the Java language. Table Icons in the Code Completion Window. While you are typing, the Source Editor checks your code and provides suggestions of how you can fix errors and navigate through code.
For the most common coding mistakes, you can see hints in the left-hand margin of the Editor. The hints are shown for many types of errors, such as missing field and variable definitions, problems with imports, braces, and other. Click the hint icon and select the fix to add. To limit the number of categories for which hints are displayed:. From the Language drop-down list, select the language and view a list of elements for which hints are displayed their checkboxes are selected.
The IDE detects compilation errors in your sources by locating and recompiling classes that depend on the file that you are modifying even if these dependencies are in the files that are not opened in the editor. When a compilation error is found, red badges are added to source file, package, or project nodes. Dependency scanning within projects can be resource consuming and degrade performance, especially if you are working with large projects.
Limit the scope of dependency scans to the Source Root search for dependencies only in the source root where the modified class is located or current Project.
In this case, the IDE does not scan for dependencies or updates the error badges when you modify a file. Select a block in your code that you want to surround with a statement and click the bulb icon in the left-hand margin or press Alt-Enter.
The editor displays a list of suggestions from which you select the statement you need. Use the Go To.. Hold down the Ctrl key and click the usage of a class, method, or field to jump to its declaration. You can also place the cursor on the member a class, method, or field. Hold down the Ctrl key and click a class, method, or field to jump to the source code, if the source is available.
Even if your last edit is in another file or project, press Ctrl-Q or use the button in the top left corner of the Source Editor toolbar. The file opens and the cursor is placed at the location of your last edit.
When you click one of the buttons, you can expand the list of the recent files and click to navigate to any of them. To toggle between files, press Ctrl-Tab to display all open files in a pop-up window, hold down the Ctrl key and press several times the Tab key to choose the file you would like to open.
The IDE's Java Editor constantly checks your code for the correct use of import statements and immediately warns you when non-imported classes or unused import statements are detected. When a non-imported class is found, the error mark appears in the IDE's left-hand margin this margin is also called the glyph margin. Click the error mark and choose whether to add the missing import or create this class in the current package.
To add an import only for the type at which the cursor is located:. If there are unused import statements in your code, press the warning mark in the Editor left-hand margin and choose either to remove one unused import or all unused imports. When working in the Source Editor, you can automatically generate pieces of code in one of the two ways: by using code completion or from the Code Generation dialog box.
In the IDE's Source Editor, you can automatically generate various constructs and whole methods, override and delegate methods, add properties and more. In the following table, multikey shortcuts are written in the following format: Ctrl-U, T. To use this shortcut, hold down the Ctrl key and press U, then release both keys and press T.

Deactivated plugins are not deleted from your installation directory, but are simply ignored by the IDE. You can re-activate them at any time. You can also choose to uninstall plugins from the IDE. Uninstalled plugins are removed from your installation directory. To use an uninstalled plugins, you need to install it again.
You use the Plugins manager to connect to the update centers to check if there are new plugins or new versions of already installed plugins available. If new or updated plugins are available, you can select, download, and install them using the Plugins manager. A plugin generally consists of a group of dependent modules. Some IDE plugins are grouped together and referred to as a Feature.
Each Feature generally corresponds to a technology and can contain a number of plugins that support that technology. When you activate or deactivate a Feature, the IDE activates or deactivates the corresponding plugins.
When you update a plugin, the update usually consists of updating one or more of the modules that make up the plugin. Some plugins may be dependent on modules in other plugins in order for the functionality to be implemented. The Plugins manager warns you when this is the case. Deactivating a plugin usually consists of deactivating the individual modules that make up the plugin.
When you use the Plugins manager to update the IDE, the IDE checks the registered update centers to see if there are new plugins or new versions of already installed plugins available. If new or updated plugins are available, you can select, download, and install the plugins using the Plugins manager. You can set the frequency that the IDE checks for updates in the Settings tab of the Plugins manager. The Plugin Installer will check for updates of installed in plugins.
If updates are available, you can step through the installer to install the updates. In addition to the default IDE Update Center, you can choose from several update centers that offer different types of plugins, such as experimental new plugins or old plugins that are no longer in regular distribution. Click the Updates tab to display available updates of installed plugins. In the left pane, select the plugins you wish to update and click Update.
The left pane of the Updates tab displays the installed plugins which have updates available from the update centers. By default, the IDE regularly checks the registered update centers for available updates of installed plugins. If no plugins are displayed in the left pane, it means that no updates were available the last time the IDE checked the update center.
Click the Available Plugins tab to display plugins that are available but not installed. If you have already downloaded a plugin's. Click Add Plugins and browse to the location of the downloaded. Select the file and click Open. Click Install and complete the pages of the installer to install the plugin. If the plugin that you have selected in the file chooser does not appear in the Downloaded tab of the Plugins manager, you probably have the same or a newer version of that plugin already installed.
You can check the Installed tab to verify that the plugin is installed and activated. The IDE enables you to deactivate installed plugins that you do not need to minimize startup time and save memory. You do not need to download the plugins again. If you want to completely remove a plugin from your local system, select the checkbox for the plugin in the left pane and then click Uninstall.
The following table defines the icons used in the Installed tab of the Plugins manager to indicate the status of plugins. If you are using a multi-user installation of the IDE, you can install a plugin globally so that the plugin is available to all users. The IDE places JAR and docs for globally installed plugins in your installation directory instead of an individual user directory. Click the Settings tab and then select Force install into shared directories in the Plugin Install Location drop-down list.
Click the Available Plugins tab, select the Install checkbox for the plugin and click Install. You can manage the registered update centers in the Settings tab of the Plugins manager. In addition to the default IDE Update center, you can add other update centers that offer different types of plugins, such as experimental new plugins or old plugins that are no longer in regular distribution.

The online help is divided into several help sets. Most help sets are packaged in a JAR file, while a few help sets are packaged in a zip file. Use the jar command-line utility to unpack the JAR file in which you are interested.
For jar-file , use the file name of the JAR file from which you want to extract files. The Jar tool makes copies of the files and writes them to the current directory. The directory structure is reproduced according to the package structure in the archive. The IDE's internationalization tools let you easily insert internationalization strings while you write your code as well as internationalize files that are already written.
You can also check resource bundles to make sure each key referenced by your code exists. When you internationalize existing source files, the IDE searches for every customizable occurrence of a quoted text string.
If you decide to internationalize the string, the IDE replaces it with a method call and adds the string to the appropriate resource bundle. You can select from several code formats for generating internationalized strings, or you can use your own custom format. As you design a form in the GUI Builder, you can have the code generated as internationalized code. The Internationalize dialog box enables you to replace hard-coded strings in a single file with internationalized strings.
If you need to internationalize several Java sources into one or more resource bundles, use the Internationalization wizard. The Internationalize dialog box opens enabling you to edit each string in the file consecutively. If a resource bundle already exists for the file, the bundle properties file in which the strings are saved is displayed in the Bundle Name field.
The Replace String field also displays a preview of the internationalized string. If no resource bundle exists for the file, the Bundle Name and Replace String fields are empty.
You can click the ellipsis If you want to add arguments to the method call, click Arguments. You can only add arguments to the method call if you use the java. MessageFormat or org. Check that the key and value are correct. By default, the Internationalize dialog box gives the key the same name as the string being replaced. To get information about the highlighted string in the Source Editor, click Info to see the name of the component containing the string and the property that the string is associated with.
The Internationalization wizard enables you to replace hard-coded strings with internationalized strings in multiple files. If you are localizing the source into more than one language, the Internationalization wizard also lets you specify the localized string for multiple locales. To automatically internationalize strings in multiple source files:.
Click Add Source s to add one or more source files to internationalize. Click Next to proceed. Click Select All if you want a single resource bundle to contain the key and value pairs for all the listed sources. To select a resource bundle for specific source files, select the desired sources and click Select Resource.
In the Select Resource dialog box, select the desired. The Init String field gives you a preview of the code that the variable will use to reference the resource bundle. To change this code, click Format and select the desired code format from the Init Code Format Editor.
In the Modify Found Strings pane, set the key name and localized values for each of the strings you want to internationalize by entering a new value in the appropriate column. Use the Source drop-down list to switch between source files. Deselect the checkbox in the first column for any string you do not want to internationalize. To change the code format used to generate the internationalized string or add arguments to the method call, click the ellipsis button The Insert Internationalized String command enables you to add internationalization strings one at a time as you create the source.
To insert an internationalized string into your source code:. In the Source Editor, put the insertion point at the location in the source file where you want to insert an internationalized string. The Insert Internationalized String dialog box appears enabling you to edit each string in the file consecutively.
To choose a different. Click Arguments if you want to add arguments to the method call. To insert an internationalized string with the GUI Builder:. In the Properties window, select the property that you want to internationalize for example, the text property of jLabel.
If a resource bundle already exists for the source, the bundle properties file into which the internationalized strings will be saved is displayed in the Bundle Name field.
If no. In the dialog box, specify an existing. Click OK to return to the property editor. If you want to change the method used to generate the internationalized string, click the Format button.
You can add arguments to the method call only if you use the java. You can check resource bundles for missing key and value pairs by using the Internationalization Test wizard.
The wizard looks for all internationalized string keys with a customizable meaning in the source and checks for a corresponding key and value pair in the specified resource bundle. You can use the wizard to add any missing pairs. Click Add Source s and select one or more source files to test in the Select Sources dialog that appears. Specify the resource bundles for the source files.
Click Select All to check one resource bundle for all the listed sources. To select a specific resource bundle for one or more source files, select the desired sources and click Select Resource.
The wizard lists all of the internationalized strings with missing key and value pairs in the selected file. The wizard automatically suggests key names and values for the string. Deselect the checkbox in the first column for any string you do not want to include in the resource bundle.
Change the key name and value for any string by typing a new value in the appropriate column. The java. MessageFormat code format lets you use strings that are constructed dynamically at runtime. The dynamically added elements are stored in an array of objects, which is passed as a parameter to java. You can use the Message Format Arguments dialog box to specify the values of these objects.
You can add arguments when you use the org. Select the java. MessageFormat format or the org. Then click OK. Use the Add and Remove buttons to add or remove message parameters. When you are done, click OK to close the dialog box. MessageFormat java. A NetBeans project is a group of source files and the settings with which you build, run, and debug those source files. In the IDE, all development has to take place within a project. For applications that involve large code bases, it is often advantageous to split your application source code into several projects.
NetBeans IDE provides wizards that enable you to create projects that are based on project templates. The IDE displays and saves any new files you create using the encoding set by the project in which they reside. If you want to change encoding properties, the IDE provides you with the ability to do so manually. The layer model prioritizes encoding based on the following hierarchy:. Project FEQ. The value of the current global project encoding in a session. If you change the project encoding property on a project that already contains files that were created using a specific character encoding, there is a risk that compiling and running the project may not succeed.
This is due to the fact that the programming compiler needs to be passed an encoding value, and there can only be one such value. Neither the IDE nor the programming language performs automatic encoding detection of files. When you change the encoding for a project, all new files are created using the new project encoding. In the Encoding drop-down list, select the character encoding that you want to be applied to the project. Click OK.
The new encoding is applied to the project you are working in. You can create groupings of projects so that you can open and close several projects at once. In addition, each group can have a different main project. After you create a project group, that project group is available in the Project Group menu.
When you select a project group from that menu, all other open projects are closed. If you select the Automatically Save Project List option in the dialog box, projects that you open or close will automatically be added to or removed from the group.
To create a project group that contains a specific set of projects:. If you created a free group and deselected the Automatically Save Project List option when you created the group, you can perform the following steps to modify the contents of the group.
Select the group or groups in the Manage Groups dialog box. Click Properties. The IDE provides tools that enable you to find, compare and move the files in your projects.
You can also modify the properties of files and create file templates that you can use when you create files. You can use the Find in Projects command to locate the occurrences of specific text strings in files in your project.
You can invoke the command from the popup menu in the Projects, Files and Favorites windows. The results of the search are displayed in the Search Results window. The Search Results window displays a node for each file that contains the search string. When a file contains more than one occurrence of the string you can expand the node to view a list of each occurrence in the file.
You can double-click an occurrence in the Search Results window to open the file in the editor at the line containing the search string. Right-click the project or folder that you want to search and choose Find in the popup menu to open the Find in Projects dialog. By default the scope is the folder that you selected, but you can use the drop-down menu to modify the scope.
You can specify how the source editor formats source code for various languages. You can specify formatting options globally to apply to all files in that language and also at the project level to specify the options for a specific project. NBI show other bugs.
