Same method in Interface and Abstract class

Question

I came to situation :

public interface Intr {
    public void m1();
}

public abstract class Abs {
    public void m1() {
        System.out.println(\"Abs.m1         


        

Answer 1

You are satisfying both conditions at once; ie. the one implementation is at the same time fulfilling the abstract class requirements and the interface requirements.

As a note, unless you are using Intr in another inheritance chain, you don't need it. Also, it might make sense to move the implements Intr up to the abstract class definition.
