Analyze the following code:

import java.util.*;

public class Test {
public static void main(String[] args) {

HashSet set1 = new HashSet();

set1.add("red");

Set set2 = set1.clone();

}
}

◦ Line 5 is wrong because a HashSet object cannot be cloned.
◦ Line 5 has a compile error because set1.clone() returns an Object. You have to cast it to Set in order to compile it.
◦ The program will be fine if set1.clone() is replaced by (Set)(set1.clone())
◦ The program will be fine if set1.clone() is replaced by (Set)set1.clone()
◦ The program will be fine if set1.clone() is replaced by (HashSet)(set1.clone())
