[Neha Daga]

question is from www.certcrunch.com

   import java.util.*;
public class Group extends HashSet {
public static void main(String[] args) {
Group g = new Group();
g.add(new Person("Hans"));
g.add(new Person("Lotte"));
g.add(new Person("Jane"));
g.add(new Person("Hans"));
g.add(new Person("Jane"));
System.out.println("Total: " + g.size());
}
public boolean add(Object o) {
System.out.println("Adding: " + o);
return super.add(o);
}
}
class Person {
private final String name;
public Person(String name) { this.name = name; }
public String toString() { return name; }
}

Do you have anything specific that you didn't understand in the question?? A,B,C and E seem the correct answer to me...

[Neha Daga]

[Neha Daga]
