Debugging Applications 

 NetBeans IDE 3.6 


To debug an application:

  1. Select the desired file in the Filesystems window.
  2. Do one of the following:
    • Choose Debug > Step Into (F7) to execute the first line in the application in the debugger and pause. Keep pressing F7 to step through the program one line at a time.
    • Open the file in the Source Editor. Then click in the left margin on any line to enter a breakpoint on that line. Choose Debug > Start Session > Run in Debugger (Alt-F5) to execute the application in the debugger up to the line containing the breakpoint.
    • Open the file in the Source Editor. Then place the insertion point on any line and choose Debug > Run to Cursor (F4) to execute the application in the debugger up to the line with the cursor.

The IDE starts executing your program in debug mode and stops at the specified line. The debugger windows at the bottom of the IDE display debugging information. For additional debugging windows, choose Window > Debugging.
