What are some effective debugging tips for IntelliJ IDEA?

Here are some effective debugging tips for IntelliJ IDEA:

1. Use breakpoints to pause execution and inspect variables.
2. Utilize the 'Evaluate Expression' feature to test code snippets on the fly.
3. Take advantage of the 'Step Into' and 'Step Over' functions to navigate through your code.
4. Use the 'Watches' panel to monitor specific variables during debugging.
5. Leverage the 'Debug' tool window to analyze the call stack and threads.

Can you explain how to set breakpoints?

To set a breakpoint in IntelliJ IDEA, simply click in the left gutter next to the line of code where you want execution to pause. A red dot will appear, indicating that a breakpoint has been set. You can also right-click the gutter and select 'Add Breakpoint' for more options.

What is the 'Evaluate Expression' feature?

The 'Evaluate Expression' feature allows you to execute arbitrary code snippets while debugging. You can access it by clicking on the 'Evaluate Expression' button in the Debug tool window or by pressing Alt + F8. This is useful for testing how changes to variables or expressions affect your program.

How can I view the call stack?

You can view the call stack in the Debug tool window. When your program hits a breakpoint, the call stack will show you the sequence of method calls that led to the current point of execution. This helps you understand the flow of your program and identify where issues may arise.
