Welcome to the IntelliJ Debugger! This guided tour will walk you through setting breakpoints, stepping through code, and watching variables change. Click "Start Tour" to begin.
Tip: In IntelliJ, start the debugger with the bug icon next to the Run button (or Shift+F9). Use F8 to Step Over, F7 to Step Into, Shift+F8 to Step Out, and F9 to Continue.
Remember: A breakpoint pauses execution before that line runs. The highlighted green line is about to execute, not already done.
In Free Mode: click the gutter (left of line numbers) to toggle breakpoints, then use the toolbar buttons to step through code.
