I am using JCreator version 5.0.0.10. And I do not know how to debug a program. Could you please specify step by step with pictures included?
JCreator LE does not have a debugger.
If you have JCreator Pro, it's just a matter of setting a breakpoint, clicking "Run" in the menu and then either "Debug File" or "Debug Project".
