Help with linking classes please

[tenhotshot]

I am a noob at java so dont look at me funny. this is a tester for a "gaming center". i have written one of the classes for it which would be the high low game here is the code for the menu(tester):

import java.util.Scanner;
import java.util.Random;
/**
 * Main Menu for all games.
 * 
 * @author (Dylan Harlow) 
 * @version (12/9/10)
 */
public class GameTester
{
    public static void main(String[] args)
    {
        //start assignments
        boolean begginer = false;
        boolean menu = false;
        boolean correctNum = false;
        boolean rightGame = false;
        boolean isInt2 = false;
        boolean startHighLow = true;
        String playans;
        int op = 0;
        highLow game1 = new highLow();
        
        Scanner begin = new Scanner(System.in);
        Scanner menu2 = new Scanner(System.in);
        
        System.out.println("Would you like to play a game?");
        while(!begginer)
          {
            playans = begin.nextLine();
            if (playans.equalsIgnoreCase("sure") || playans.equalsIgnoreCase("yes") || playans.equalsIgnoreCase("ya") || playans.equalsIgnoreCase("love to") || playans.equalsIgnoreCase("i'd love to") ||  playans.equalsIgnoreCase("yes ") || playans.equalsIgnoreCase("love to") || playans.equalsIgnoreCase("ok") || playans.equalsIgnoreCase("yeah") ||
            playans.equalsIgnoreCase("id love to") || playans.equalsIgnoreCase("uh huh") || playans.equalsIgnoreCase("absolutely") || playans.equalsIgnoreCase("of course") || playans.equalsIgnoreCase("course") || playans.equalsIgnoreCase("obviously") || playans.equalsIgnoreCase("yep") ||  playans.equalsIgnoreCase("yup") ||  playans.equalsIgnoreCase("course"))
            {

            }
            else if (playans.equalsIgnoreCase("no") || playans.equalsIgnoreCase("no thanks") || playans.equalsIgnoreCase("nope") || playans.equalsIgnoreCase("no thank you"))
            {

            else
            {
                System.out.println("Come on now... enter something that resembles a yes or no.");
            }
        }
        while(!menu)
        {
            while(!rightGame)
            {
                System.out.println("Which game would you like to play?");
                System.out.println("[1] High Low");

                rightGame = true;
            }
            isInt2 = false;

           while (!isInt2)
    
           try 
           {
               op = menu2.nextInt();
               isInt2 = true;
            } 
            catch (Exception a) 
            {
                System.out.println("Please enter the number of the game you wish to play in digit form or 0 to quit. ");
                menu2.nextLine();
            }
            if (op == 1)
            {
                menu = true;
                startHighLow = false;
            }
            else if (op > 1 && op < 6)
            {
                System.out.println("Sorry this game is under constrction please choose another.");
            }
            else if (op == 0)
            {
                menu = true;
                correctNum = true;
                begginer = true;
                System.out.println("Thanks for Playing! Goodbye.");
            }
            else
            {

            }
        }
        }
    }

And here is the HIGH LOW game:

                }
            
            
        }
    }
}
}
}

All i want to do is make it so when a user inputs something in the tester the program will go to the highLow class and do everything in there. and if they want to go back to the main menu(tester) they have to option to. CAN SOMEONE PLEASE HELP??

public class One {

}
