If I am in here for the second time within a few hours, should I delete my previous entry so that I don't swamp your friends page?


In a class called Menu, I have this code:

public static int selection(byte selection) throws IOException
{

		int index = 0;

		if(selection == 1)
		{
	        	System.out.println("You chose 1");
			index = 3;
		}
		else if(selection == 2)
		{
			System.out.println("You've selected #2");
		}
		else if(selection == 3)
		{
			System.out.println("You've selected #3");
		}
		else if(selection == 4)
		{
			System.out.println("You've selected #4");
		}
		else if(selection == 0)
		{
			System.exit(0);
		}
		else
		{
			System.out.println("I'm sorry, you haven't entered a valid option. Please try again.");
			display();
		}

		return index;

}

This code is called in my main method. Within the main method, at the beginning, I have set index to zero. I was hoping that by calling Menu.selection(selection) where selection is equal to 1, I would have returned the value of index as 3. But if, after calling Menu.selection(selection) in the main, I print out the value of index... it is zero.

Any idea?
