How to make a game quit in BlueJ after entering a room

[alpdog14]

I am new to BlueJ and programming and I have a game application that runs exactly how I want it too except I want the game to quit once I enter a room called "DungeonRoom" which extends the "Room" class. Here is my code for the DungeonRoom:

import java.util.ArrayList;

public class DungeonRoom extends Room
{
 
    private boolean isAlive = false;
    private boolean finished = false;
    /**
     * Constructor for objects of class DungeonRoom
     */
    public DungeonRoom(String description)
    {
        super(description);
       while (! finished) {
            //Command command = parser.getCommand();
            //finished = processCommand(command);
            if (hasDied()) finished = true;
       }
        System.out.println("Thank you for playing.  Good bye.");      
    }
    
   public boolean hasDied() {return isAlive == false;}
    public void die() {isAlive = false;}

}

Currently when I try to run my game after adding the while statement it completely freezes and I have to Crtl-alt-delete End the task. Can anyone guide me on how I can have this game quit once I get into this room.

System.exit(0) ends the program. I don't think it will close the game though.

Is your game displayed in a GUI or text based through command prompt or displayed in an IDE or what?

its using BlueJ in the terminal window so that would be command prompt, right?

when i tried to add the System.exit(0); to the code and removing all the rest of the code, so basically all I had was

public DungeonRoom(String description)
{
super(description);
System.exit(0);
}

The game object does not even get created on the workbench.
