in java string is an object. so when i evaluate if(s1==s2) , the test condition is evaluated as false. because both string object refers to different memory location even if contents are same. so output of this program should be different but when i run this progarm , output is same.
When you create a String literal it automatically goes into the String pool. Whenever you create another reference to the same literal it refers to the String already in the pool. A new String object is not created.
