I am still confused with the equals method functioning ??
I am still not able to catch why it is behaving so differently
in wrapper classes??


Long l1 = new Long(7);
Integer j = new Integer(7);
System.out.println(l1.equals(j));//false????

Object A = new Long(7);
Long l2 = new Long (7);
System.out.println(A.equals(l2));//true

Long l1 = new Long(7);
Integer j = new Integer(7);
System.out.println(l1.equals(j));//false????
//See carefully! here l1-->Long j --->Integer
//Both refs are diff class types . So it is false.

Object A = new Long(7);
Long l2 = new Long (7);
System.out.println(A.equals(l2));//true

//Now see here!! A-->Object l2 --->Long (Implicitly Object)
//Both refs are same class types So it is true.

For the Wrapper classes's equal(Object o) to return true the argument and the ref types MUST be same class type
