You'll need to use reflection:

edit: Question already asked here: Is it possible to use Java Reflection to print out attributes of the parent class?

Sample Code:

public class Test {

    public static void main(String[] args) {
        System.out.println(Test.class.getMethods().length);
        System.out.println(Test.class.getFields().length);
    }

}

Best not to answer `homework` questions with the actual code, but rather (as Walkerneo did) with a pointer to how to proceed to build one's own solution. – T.J. Crowder Mar 28 '12 at 07:48

This sounds like you are asking us a homework question. Look at the Reflection API, in package java.lang.reflect and the Class class. Then when you have some code you want us to help with, post again.
