is why is this question contradicting what k&B says?

[Ankur kothari]

   class B {
  public static void main(String[] args) {
    Boolean b1 = new Boolean(true);
    Boolean b2 = new Boolean(true);
    Boolean b3 = new Boolean("TrUe");
    Boolean b4 = new Boolean("tRuE");
    System.out.print((b1==b2) + ",");
    System.out.print((b1.booleanValue()==b2.booleanValue()) + ",");
    System.out.println(b3.equals(b4));
}}
 

Prints: false,true,true

k&B says that when Boolean are compared with == their primitives are actually compared. so b1==b2 should be true. but danchisholm mock test gives other answer...why?

What do you think are compared, are the boolean values compared or the referrences to the Boolean wrapper object compared.

dude check k&B page 246

oooops.....my bad.......

[Nitish Bangera]

I guess you need to check the proper declaration types of Wrappers. Why not try using the String s = "1" and String s = new String("1") types....
