A command similar to Goto in Java?

[Dan Bolens]

Right now my program is supposed to allow users of repeat the program over again or allow them to restart if they make an error. My code is as follows:

else {
	
	String yes;
	yes = JOptionPane.showInputDialog("One of your shapes is invalid, would you like to try again? (Y or N): ");
	
	if (yes.equals("Y")) {
		
	}
	
	if (yes.equals("N")) {
		
		System.exit(0); 
	}
}

If the user enters "N", the program terminates, but how can I make the program start over again if the user says "Y"? I've been looking for something similar to a GOTO statement (which I know you should NEVER use), and I've found the throw and switch commands. I'm a bit confused to how both of these commands work, and how I could fit them into my program. Any help would be much appreciated!

Use a loop. Something like this would do the trick.

boolean cont = false;
do{
    // your codes to be repeated
    cont = // true to repeat, false to exit.
}while(cont);
