Java Covariants

Question

public class CovariantTest {
    public A getObj() {
        return new A();
    }

    public static void main(String[] args) {
        CovariantTest c = new SubCov         


        

Answer 1

Replace your A and B above with:

class A {
    public int getX() { return 5; }
}

class B extends A {
    public int getX() { return 6; }
 }

That will probably answer your question about what is wrong ;-)
