- Breakpoints in Java.
- Multiple simultaneous debugging sessions.
- Customizable breakpoint properties: conditions, pass count, etc.
- Frames, variables, and watches views in the debugger UI.
- Runtime evaluation of expressions.

General debugging steps
- Configure the dependencies and libraries to be passed to the compiler and generate the debugging information.
- Configure common debugger behavior, including stepping speed, class reloading policy, or scrolling of the editor canvas.
- Configure the debugger engine.
- Define a run/debug configuration for the application to be debugged.
- Create breakpoints in the source code.
- Launch a debugging session.
- Pause or resume the debugging session as required.
- During the debugger session, step through the breakpoints, evaluate expressions, change values on-the-fly examine suspended program, set watches, reload classes, and customize views.
After you've started a debug session, the icon that marks the Debug tool window toggles to to indicate that the debug process is active.
Note that IntelliJ IDEA lets you debug decompiled code in the same way as your normal source files, provided that it contains line number attributes.
