    Please explain what the error is. If you get error messages, copy the full text and paste it here.

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.

    The catch block should call the printStackTrace() method to give a full error message.
    If you don't understand my answer, don't ignore it, ask a question.

    The code you have never initialize the integers so you cant use them in your code.
    You should give them a value before you use them.

    And i noticed too that you called your class "new" which is a keyword and cant be used as a class name, this is probaly your first problem what stands above is your second problem.
