Here is the code i got below, i dont know if anyone knows whats wrong as i been stuck. I am total novice, so to get this far for me is a achivement just been using the book over the weekend but was hoping someone could help me out

import java.util.Scanner;

public class InterfaceControl
{
	public static void main (String[] args)
	{
		// this is the starting point for the whole thing
		InterfaceControl ic = new InterfaceControl()
		boolean loggedIn = false;

		loggedIn = ic.login();

		while (!loggedIn)
		{
			// let them keep trying to log in
			loggedIn = ic.login();
		}

		// they reached this point so they must be logged in
		ic.showMenu();
	}

	public void showMenu()
	{
			System.out.println("======Welcome to the main menu====\n" );
			System.out.println("Type 0: Exit.\n" );
			System.out.println("Type 1: View Ski Run Length\n" );
			System.out.println("Type 2: View Limits of Skiers \n" );

			
		Scanner st = new Scanner (System.in);
		System.out.println ("\n");
		System.out.println ("\t" + "Enter choice of option." );
		
			choice=st.nextInt();
			int choice = st.nextInt();

			if (choice == 1)
			{
				otherClass.viewrunlengths();
			}
			else if (choice == 2)
			{
				otherClass.viewlimitsofskiers();
			}
			else if (choice == 0)
			{
				System.exit();
			}
		}
	}

	public boolean login()
	{
			public static boolean loginSuccessfull()
	{
		
		Scanner st = new Scanner (System.in);
		System.out.println ("\n");
		System.out.println ("\t" + "Enter Username." );
		System.out.print("\t");		
		String userName = st.nextLine();
		
		System.out.println ("\n");
		System.out.println ("\t" + "Enter Password ." );
		System.out.print("\n");		
		String password = st.nextLine();
		
		if( Security.checkLogin(userName, password) == true )
		{
			return true;
		}
		else
		{
			return false;
		}
	}
	}
}

Code (markup):

 

if your logged in try "showMenu()" it should work.
