So the output will be,

System.out.println(s1 == s2); : false
System.out.println(s1 == s3); : false
System.out.println(s2 == s3); : true

Am I right?

well the intern method is mostly not relevant. this is because when you pass a string into a string constructor, it is always created into the pool. so why would someone do this

s = new String("hello").intern()

when

s = "hello"

will also result in the same behavior... Actually it will work in some special cases... although I don't know which are they...
