string doubt second one

[Karu Raj]

String s1 = new String("amit");
System.out.println(s1.replace('m','r'));
System.out.println(s1);
String s3="arit";
String s4="arit";
String s2 = s1.replace('m','r');
System.out.println(s2==s3); //XYZ
System.out.println(s3==s4);

Why is the out put at XYZ is false ?though both reference to same "arit"

I think both s2 and s3 do not refer to same object.
s2 refers to a String Object in pool, whereas s3 refers to a new object created by the statement earlier:
String s2 = s1.replace('m','r');
replace method always returns a new String Object even if that string is already present in the pool.

Correct me if I am wrong.
