I have come across this question and i thought true should be printed in 2nd case as Strings in constant pool sharing same reference but it returns false.

Your String s3 is not in the constant pool.

From the Java Language Specification section 15.8.1 (talking about the String Concatenation operator +):


The String object is newly created unless the expression is a constant expression.



Your expression 's1 + s2' is not a constant expression, so the result is a new String object.
