Question

Look at two classes below. Class B extends class A and overrides “toString()” method.

If you have instance of class B, how can you call “toString()” method of class A?



public class A {

public A() {}

public String toString() {

return "Class A";

}

}



public class B extends A {

public B() { super(); }

public String toString() {

return "Class B";

}

}

public static void main(String[] args) {
B objectB = new B();

String stringB = objectB.toString();

// Here find a way to call toString() method of the superclass of objectB

String stringA = ...

}

Explanation / Answer

class A { public String toString() { return "A toString()"; } } class B extends A { public String toString() { return "B toString()"; } public String superString() { return super.toString(); } } public class Test { public static void main(String[] args) { A a = new B(); System.out.println(a.toString()); System.out.println(a.superString()); } }
