Launching a Java Program
    
    
The simplest way to launch a Java program is to run it using a Java 
  Application  launch configuration. This launch configuration type 
  uses information derived from the workbench preferences and your program's Java 
  project to launch the program. 
    
  -  In the Package Explorer, select the Java compilation unit 
    or class file with the main method you want to launch. 
- Press the Run [  ] button in the workbench toolbar or select Run > Run 
    from the workbench menu bar. Alternatively, select Run As > Java 
    Application in the Package Explorer pop-up menu, 
    or select Run > Run As > Java Application in the workbench 
    menu bar, or select Run As > Java Application in the drop-down 
    menu on the Run tool bar button. ] button in the workbench toolbar or select Run > Run 
    from the workbench menu bar. Alternatively, select Run As > Java 
    Application in the Package Explorer pop-up menu, 
    or select Run > Run As > Java Application in the workbench 
    menu bar, or select Run As > Java Application in the drop-down 
    menu on the Run tool bar button.
-  Your program is now launched, and text output is shown in the Console 
    View. 
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 main method.  (If only one class with a 
  main method is found in the project, that class is launched as if you selected 
  it.)
