Noobie to Java questions!! :D

Hi all, I'm new to Java and am experiencing some difficulty with this assignment I have...

I have programmed an interface with a bunch of non static methods and now when i extend that program to another class, I can't use the methods because they are non-static! :S What's the catch here?

Thanks in advance!!

You don't extend an interface... you implement it. To use the methods found inside the interface, you must create an object of that type first. Ex.:

Code :

---

public class A
{
    // here is a non-static, or instanced method
    public void doIt()
    {
        System.out.println("hello world! this is an instanced object.");
    }
}

---

To use/call a non-static method:

Code :

---

public static void main(String[] args)
{
    A myObject = new A(); // instance it
    myObject.doIt(); // call the method with the myObject instance
}

---

Ah, but the real question is whether the 'interface' is an interface or a GUI. I suspect the latter.

Thank you very much for the answers, I hadn't quite understood the whole instancing thing, but helloworld922's post fixed it! I can use my methods now! :D
