Java editor
The Java editor provides specialized features for editing Java code.
Associated with the editor is a Java-specific Outline view, which shows the structure of the active Java compilation unit. It is updated as the user edits the compilation unit.
The Java editor can be opened on binary CLASS files. If a JAR file containing the CLASS files has a source attachment, then the editor shows the corresponding source.
The editor includes the following features:
- Syntax highlighting
- Content/code assist
- Code formatting
- Import assistance
- Quick fix
- Integrated debugging features
The Java editor can be configured to either show an entire compilation unit or a single Java element only. To change the setting, use the toolbar button Show Source of Selected Element Only.
The most common way to invoke the Java editor is to open a Java file from the Navigator or Package explorer using pop-up menus or by clicking the file (single or double-click depending on the user preferences). You can also open the editor by opening Java elements, such as types, methods, or fields, from other views.
