4.9. Running Your Code

Problem

You want to run your code.

Solution

Select one of the following items in the Run menu:

Run→ Run Last Launched

Runs the last launched program

Run→ Run History

Enables you to select programs to run from a submenu

Run→ Run As

Enables you to select how to run a program—with the Java Applet, Java Application, JUnit Test (discussed in Chapter 5), or Run-time Workbench

Run→ Run

Enables you to set the launch configuration and run your code

Discussion

Before running your code, save your files, or Eclipse will prompt you to do so. The general way to run your code is to select Run→ Run As, and then choose the way you want to run your code from the submenu: Java Applet, Java Application, JUnit Test, or Run-time Workbench (used to run plug-ins under development).

Tip

The Run→ Run History and Run→ Run Last Launched menu items give you handy shortcuts for running recent programs.

Eclipse 3.0

Eclipse 3.0 adds another option to the Run→ Run As submenu: JUnit Plug-In Test. Eclipse 3.0 makes JUnit available for plug-in development.
