Moving Through Code While Debugging

The JDeveloper debugger lets you control the execution of your program; you can control whether your program executes a single line of code, an entire method, or an entire program block. By manually controlling when the program should run and when it should pause, you can quickly move over the sections that you know work correctly and concentrate on the sections that are causing problems. To set how you want the debugger to start debugging, see Setting the Debugger Start Options.

The debugger lets you control the execution of your program in the following ways:

The Step Into and Step Over commands offer the simplest way of moving through your program code. While the two commands are very similar, they each offer a different way to control code execution.

The smallest increment by which you step through a program is a single line of code. Multiple program statements on one line of text are treated as a single line of code; you cannot individually debug multiple statements contained on a single line of text. The easiest approach is to put each statement on its own line. This also makes your code more readable and easier to maintain.
