whizlab question for SCJP1.5

[Nazeer Ahmed]

Hi

In whizlabs fpr SCJP1.5 i got a question

Vector<Integer> vector1= new Vector<Integer>();
Vector<Double> vector2= new Vector<Double>();
System.out.println("== "+ vector1.getClass()==vector2.getClass());
System.out.println("equal "+ vector1.equals(vector2));

where the correct answer put up as
true
true

But when i execute the same program i am getting compile time error as

incomparable types: java.lang.String and java.lang.Class <capture of ? extends java.util.Vector>

Please clarify about the program output...

Thanks.

See comment in code:

import java.util.*;
public class Funny
{
    public static void main(String[] args) {
        Vector<Integer> vector1= new Vector<Integer>();
        Vector<Double> vector2= new Vector<Double>();
        System.out.println("== "+ (vector1.getClass()==vector2.getClass()));  // needs extra parentheses
        System.out.println("equal "+ vector1.equals(vector2));
    }
}
 
This is the sort of error an SCJP candidate should be able to correct.
