What are some common debugging issues I might encounter?

I keep getting a null pointer exception. What does that mean?

A null pointer exception occurs when your code attempts to access an object or variable that hasn't been initialized. Check your variable assignments.

How can I effectively track down the source of this exception?

You can use debugging tools like breakpoints, logging, or stack traces to trace the flow of your program and identify where the null reference occurs.

Are there any best practices to avoid these issues in the first place?

Yes, some best practices include thorough testing, code reviews, and using defensive programming techniques to handle potential null values.
