    I suggest you read the following tutorial to help you learn to do this: Classes (The Java Tutorials). As is, you can a) call a static method from the main, b) create a new object and call a method of said object, c) do the math in main accessing the values of a created object d) its probable I missed another way. For example, a)
    public class Something{
        public static int sum(int a, int b){
            return a+b;
        }
    }
    //
    Something.sum(1,2);//perform the sum

    Two ways.

    One, make it a static method and do this in the main method

    System.out.println(className.Amr(2,3));

    Or use the constructor of your first class to make an object of that class then

    System.out.println(object.Amr(2,3));
