How does inheritance in Java work?

Question

We have next classes:

class Super {
    void foo() {
        System.out.println(\"Super\");
    }
}

class Sub extends Super {
    void foo() {
        super         


        

Answer 1

when you write super.foo(); you are calling the superclass method.

The foo method of class sub overrides the foo method of Super by adding an instruction to the super class method.
