Function Call Question

Can someone tell me how I would I call a Function in Java?

For a non-static method you would need a handle to an object. For a static method you can just make the call via the class name.

Code:

---

public class X{
    public static void main(String[] args){
 
    String s = String.valueOf(525); static call
    System.out.println(s);
    String s2 = s.substring(0,2); // non-static call
    System.out.println(s2);
 }
}
