IntelliJ IDEA 2016.1 Help

Running Applications

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

IntelliJ IDEA makes use of the settings defined in a Run/Debug Configuration. All the run configurations that exist in a project, are available in the Select Run/Debug Configuration drop-down list:

Running an application

To run an application, follow these steps:

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

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

altShiftF10

From this pop-up menu you can:

  • Invoke the Edit Configuration dialog.
  • Edit the selected configuration before launch (F4).
  • Instantly delete a temporary configuration (Delete).
  • Switch from run to debug and vice versa (holdShift).
  • 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 and in the Run/Debug Configuration Selector toggles to active_run_icon to indicate that the run process is active.

If you want to see a list of all currently running applications, select Run | Show Running List from the main menu. A popup listing all active applications will be displayed in the top-right corner of the editor.

Running a class with a main() method

To run a class with a main() method, follow these steps:

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