Week 6 [Fri, Sep 9th] - Tutorial

During the tutorial, demo your ability to do debugging using an IDE by performing the following tasks:

1. Set a breakpoint in the following method of the Main class.

   /** Reads the user command and executes it, until the user issues the exit command.  */
   private void runCommandLoopUntilExitCommand() {
       Command command;
       do {
           String userCommandText = ui.getUserCommand();
           command = new Parser().parseCommand(userCommandText);
           CommandResult result = executeCommand(command);
           personBook.setLastShownList(result.getRelevantPersons());
           ui.showResultToUser(result);
   
       } while (!ExitCommand.isExit(command));
   }
   

2. Use the debugger to step through the code while explaining how the code works. Start from the main method.
3. Suppose the code behaves incorrectly when using the list command after adding two persons. Show how to set a conditional breakpoint so that execution pauses when the user types in the command list but doesn't pause for other commands.
   You need to set what is known as a conditional breakpoint.
