| Java Editor |
| </h1> |
| <p> |
| The Java editor provides specialized features for editing Java code. |
| </p> |
| <p> |
| 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. |
| </p> |
| <p> |
| |
| The editor can also show a breadcrumb navigation bar. The breadcrumb shows the parent chain |
| of the element at the current cursor position. It is also updated when the user edits the |
| compilation unit or changes the selection. |
| </p> |
| <p> |
| 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. |
| </p> |
| <p> |
| The editor includes the following features: |
| </p> |
| <ul> |
| <li>Syntax highlighting |
| </li> |
| |
| <li>Content/code assist |
| </li> |
| <li>Code formatting |
| </li> |
| <li>Import assistance |
| </li> |
| <li>Quick fix |
| </li> |
| <li>Integrated debugging features |
| </li> |
| </ul> |
| |
| <p> |
| 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 <span class="control">Show Source |
| of Selected Element Only</span>. |
| </p> |
| <p> |
| The most common way to invoke the Java editor is to open a Java file from the 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. |
