25.15.1. Basic Steps

Try these first

1. 1.

   What is a breakpoint?

   Hint

   Think of where you would stop to look at something in your code.

2. 2.

   Describe what happens when you run your code in debug mode.

   Hint

   Consider the difference between regular execution and the state of debugging.

3. 3.

   What does a breakpoint do in debugging?

   • A. Terminates the program
   • B. Pauses execution at a specific line
   • C. Automatically fixes bugs

   Hint

   It's a marker where the debugger stops.

4. 4.

   True or False: Running in debug mode allows the use of breakpoints.

   • True
   • False

   Hint

   Consider the role of the debugger.

5. 5.

   You are debugging a program that has an unexpected output. Explain how you would use breakpoints and stepping features to identify the problem.

   Hint

   Focus on where values diverge from expectations.

6. 6.

   If you encounter a NullPointerException, outline the steps you would take using debugging tools to resolve it.

   Hint

   Consider the last method that manipulates the variable.
