• Breakpoints: These are the cornerstones of debugging. You set breakpoints in your code, and the debugger pauses execution at those points, allowing you to examine the program’s state. There are several types of breakpoints available:
  • Line Breakpoints: Pause execution at a specific line of code.
  • Method Breakpoints: Pause execution when a specific method is entered or exited.
  • Field Watchpoints: Pause execution when a specific field is accessed or modified.
  • Conditional Breakpoints: Pause execution only when a specified condition is met, saving you time by filtering out irrelevant pauses.
• Step-by-Step Execution: The debugger provides a suite of step commands to control the execution flow:
  • Step Over (F8): Executes the current line and moves to the next line in the same method.
  • Step Into (F7): Enters the method called on the current line, if applicable.
  • Step Out (Shift+F8): Executes the remaining lines of the current method and returns to the calling method.
  • Force Step Into (Alt+Shift+F7): Similar to Step Into, but can enter methods even if they are marked as “no step into”.
• Variable Inspection: During debugging, you can inspect the values of variables at any point. The debugger displays the current values, allowing you to track how they change over time and identify potential issues.
• Evaluate Expression: You can evaluate any valid expression within the current context. This is incredibly useful for testing hypotheses or calculating values without modifying your code.
• Frames View: This view displays the call stack, showing the sequence of method calls that led to the current point of execution. This is extremely helpful in understanding the overall program flow.
• Threads View: If your application uses multiple threads, this view allows you to inspect the state of each thread, making it easier to identify and resolve concurrency issues.
