Running Applications

Introduction

IntelliJ IDEA enables running entire applications as well as classes with the 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.

If you want to see the list of all currently running applications, select Run | Show Running List from the main menu. Refer to the Viewing Running Processes section for details.
