How to restart Java GUI application?

So I ran into this problem while creating a game.  When the user loses he's given the option to play again.  If he says yes, I have to set everything as a new game.

How do I go about doing this?

I mean, is there a simple way to do it?  I have like 100 object and it'd be ridiculous to make new objects.

try putting it in a while loop. when the game is over, the user is asked to start again, if the user says yes, you start the loop over, else you end the loop and the program is over.
while(a){

//game code

String x = JOptionPane.showInputDialog(null,"Would you like to play again?");

if(x.equalsIgnoreCase("no")

   a = false;

}

JOptionPane.showMessageDialog("Thank you for playing!");

not really, you would put the while loop in the main method, and set the frame visiable inside the loop, along with the rest of the game code and pretty much everything.

also instead of the above code also, do this:
while(a){

//game code

Object[] x = {"Yes","No"};

		int y = JOptionPane.showOptionDialog(null, "Would you like to play again?", "My Game", JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE, null, x, x[0]);

if(y == 1)

  a = false;

}

JOptionPane.showMessageDialog("Thank you for playing!");

In my main method?

This is my main method.... I ask the user if they want to keep playing in the game class... so not sure how I would do it inside the main method.


 

public class BattleshipApp {
 
 
 

	public static void main(String[] args) {

		

			

			GameBoard g = new GameBoard();

			g.setVisible(true);

			g.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

			

		

			

		}
 

	}

try this and tell me if it works:


while(a){

GameBoard g = new GameBoard();

g.setVisible(true);                  g.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 

Object[] x = {"Yes","No"};

int y = JOptionPane.showOptionDialog(null, "Would you like to play again?", "My Game", JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE, null, x, x[0]);

if(y == 1)

  a = false;

}

JOptionPane.showMessageDialog("Thank you for playing!");

Thanks for your help. You code kept showing the would you like to play again message in an infinite loop.  I had to turn in my project already so I just sent what I had.  Thanks for your help again.

well, did you have a declared as boolean a = true; before the while? I assumed you would do so yourself...I tested this code myself and does not lead to an infinite loop....
