| <h1>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 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 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.</p> |
