== it compares objects references( reference means memory location), the both objects are in different location in memory so when u compare these objects with ==, it returns false, because these sind different objects, altough these contain same string :), i hope, i can help u.

s1 == s2 is a true or false evaluation. It's like asking "is the reference at s1 equal to the reference at s2?" . The answer would be false, since they occupy different addresses in memory. If you want to see if two strings hold the same values use s1.equals(s2) as your evaluation.
