java - Interface and Abstract class ad method overriding

Here is the code:

interface hi
{
    public void meth1();
}
abstract class Hullo
{
    public abstract void meth1();
}
public class Hello extends Hullo implements hi
{
    public void meth1(){}
}

Question:The code compiles and everything. I wanted to know the meth1() in class Hello is overriding which meth1()? The ont in the interface or the one in the abstract class and why?

The answer is short: Both.....

In fact, to be correct: You are overriding none of them, you are implementing them both, with one method.
