| Launching a Java Program |
| </h1> |
| |
| <p>The simplest way to launch a Java program is to run it using a<strong> Java |
| Application </strong> launch configuration. This launch configuration type |
| uses information derived from the workbench preferences and your program's Java |
| project to launch the program. </p> |
| |
| <ol> |
| <li> In the <strong>Package Explorer</strong>, select the Java compilation unit |
| or class file with the main method you want to launch. </li> |
| <li>Press the <strong>Run</strong> [ <img src="../images/org.eclipse.debug.ui/etool16/run_exc.png" width="16" height="16"> |
| ] button in the workbench toolbar or select <strong>Run > Run</strong> |
| from the workbench menu bar. Alternatively, select <strong>Run As > Java |
| Application</strong> in the <strong>Package Explorer</strong> pop-up menu, |
| or select <strong>Run > Run As > Java Application </strong>in the workbench |
| menu bar, or select <strong>Run As > Java Application </strong>in the drop-down |
| menu on the <strong>Run</strong> tool bar button.</li> |
| <li> Your program is now launched, and text output is shown in the <a href="../reference/views/console/ref-console_view.htm"><strong>Console |
| View</strong></a>. </li> |
| </ol> |
| |
| <p>You can also launch a Java program by selecting a project instead of the compilation |
| unit or class file. You will be prompted to select a class from those |
| classes that define a <em>main</em> method. (If only one class with a |
| main method is found in the project, that class is launched as if you selected |
| it.)</p> |
