    try
    {
    Thread.sleep(2500);
    }
    catch(InterruptedException e)
    {
    System.out.println(e.getStackTrace());
    }

    } //end of class welcome

public static void menu() {
    int choice;

    do{

}

}

and i would like to get the some integers from the mtdmathquiz(); , mtdcompquiz(); , mtdengquiz(); , mtdranquiz(); to menu();. The integers/variables that i want to be able to use are: mathcount, compcount, engcount and rancount. PLEASE HELP!
