        bool boolResult;
        boolResult = String.Equals("bbc", "bbc");
        Console.WriteLine("String.Equals(\"bbc\", \"bbc\") is " + boolResult);
        boolResult = myString.Equals(myString2);
        Console.WriteLine("myString.Equals(myString2) is " + boolResult);
        boolResult = myString == myString2;
        Console.WriteLine("myString == myString2 is " + boolResult);
    }
}
