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);	} }
