IntelliJ IDEA 14.1.0 Help

Running Applications

IntelliJ IDEA enables running entire applications as well as classes with a main() method .

When running an application, IntelliJ IDEA uses the settings defined in the Run/Debug Configuration dialog box. All run configurations that exist in a project, are available in the Select Run/Debug Configuration drop-down list on the main toolbar:


To run an application

  • On the main toolbar, select the desired run configuration, and do one of the following:
    • Choose Run | Run on the main menu.
    • Click img.
    • Press Shift+F10.

Alternatively, you can press Shift+Alt+F10, select the desired run configuration from the pop-up menu, and press Enter.


From this pop-up menu you can:

  • Invoke Edit Configuration dialog.
  • Edit the selected configuration before launch (F4).
  • Instantly delete a temporary configuration (Delete).
  • Switch from run to debug and vice versa (hold Shift).
  • Access a previously selected configuration (1).
  • Access context-dependent configuration (2 or 3).

This pop-up menu can also be quickly accessed by pressing F9, when you're not running any debug session.

Note that after you've started a run session, the run icon that marks the Run tool window toggles to active_run_icon to indicate that the run process is active.

To run a class with a main() method, do one of the following

  • Open the class in the editor and choose Run <method name > on the context menu or press Ctrl+Shift+F10.
  • Select the class in the Project tool window and choose Run <method name > on the context menu of the selection.
