4. Debugging Program in NetBeans
4.1. Other Debugger's Features:
Modify the Value of a Variable
You can modify the value of a variable by entering a new value in the "Variable" panel. This is handy for temporarily modifying the behaviour of a program, without changing the source code.
Step-Into and Step-Out
To debug a method, you need to use "Step-Into" to step into the first statement of the method. You could use "Step-Out" to return back to the caller, anywhere within the method. Alternatively, you could set a breakpoint inside a method.
