Comment on Tutorial : equals( ) Versus == in Java By Mashoud
There is no need to fight. ...whatever ku is saying is correct and what arpita experienced is also correct.
Ku will be correct if I say
String s1 = "Hello";
String s2 = "Hello";
the big difference is here I am not explicitly creating a new object , instead if I had used String s2 = new String ("Hello") just like in thread 1 then I will get s1 == s2 not true which arpita got. Arpita if you try s2 = "Hello" in your program you may get true (depends on your jvm)

One more thing what ku said is JVM specific, a particular JVM can choose to maintain String pool while other may not.
String API just guarantees that equals() will work as intended but not == .
