Thread: Menu Problem

Ahoy. I'm trying to write me a menu driven program, and I'm having a heck of a time figuring out how to break out of a loop and up a level.

Scanner stuff here, user input variable from keyboard object,etc.
boolean menu = true;
if (!menu)

(input == 1)
Display "You picked menu 1. You can now pick a cat or dog."
Get input here.
if (choice == dog)
Do X
else if (choice == cat)
Do Y
else
Go back to the first menu.

else if (input == 2)
Do something else.


How do I get it to break out of the nest if statement and "re run" the first menu? I'm trying to build a list of nested menus and it's driving me nuts.

How do I get the external loop to start over tho?

I think I got it. Here's the code for anyone who needs some help with this in the future:

		boolean run = false;
		boolean run2 = false;
		do
		{
			System.out.println("Introduction.");
			System.out.println("Menu 1 ( 1, 2, or 3)");
			int menu1 = input.nextInt();
 
			if (menu1 == 1) 
			{
 
				do	{
					System.out.println("Menu Level 2, option 1 - Select next level: ( 4, 5, 6 (Go back)");
					int menu2 = input.nextInt();
					if (menu2 == 4)
					{
						System.out.println("Menu 2, option four.");
 
					}
					else if (menu2 == 5)
					{
						System.out.println("Menu 2, option 5");
 
					}
					else if (menu2 == 6)
					{
						System.out.println("Breaking out of menu level 2, going back to menu level 1");
						break;
					}
 
				}
				while (!run2);
			}
 
 
			else if (menu1 == 2)
			{
 
				do	{
					System.out.println("Menu Level 2, option 1 - Select next level: ( 4, 5, 6 (Go back)");
					int menu2 = input.nextInt();
					if (menu2 == 4)
					{
						System.out.println("Menu 2, option four.");
					}
					else if (menu2 == 5)
					{
						System.out.println("Menu 2, option 5");
					}
					else if (menu2 == 6)
					{
						System.out.println("Breaking out of menu level 2, going back to menu level 1");
						break;
					}
 
				}
				while (!run2);
			}
 
		} while (!run);
		}
}
