Debugging Tips

Suppose you wrote your program and made it bulletproof by catching and properly handling all exceptions. Then you run it, and it does not work right. Now what? (If you never have this problem, you can skip the remainder of this chapter.)

We discuss the debugger later in this chapter. In this section, we offer you a number of tips that may be worth trying before you launch the debugger.
