How to run the last launched application

The answer lies in a preference hidden on the Run/Debug page:

• Go to Window > Preferences > Run/Debug > Launching.
• Select the option Always launch the previously launched application. It’s located at the bottom of the dialog.

The preference should look something like this:

Now you’re free to press F11, Ctrl+F11 or click the Run/Debug icons on the toolbar with confidence, knowing it’s going to run what you expect it to run.

One question arises: How do you quickly run a class as a specific application (eg. a JUnit test) if you can’t press F11 to run it? You have some options available:

• The fastest way is to use keyboard shortcuts. Eclipse allows you to launch classes using a keystroke, including JUnit tests, Java applications, etc using Alt+Shift+X.
• Alternatively, right-click on the class and select Run As. The submenu will show available options for launching the class.
• Lastly, you could click the pulldown arrow on the run/debug icons in the toolbar and select Run As. The submenu once again shows available options for launching the class.
