I compiled and ran your code using 1.5.0, and got "False False" as output. (The toString method is creating new Strings at runtime, so these are different references.)

Can you verify your output?

The output I get is "False False." The toString method of Byte is returning a new runtime String instance each time it's called, and == is a shallow comparision of references.

b1.toString() is one reference, and b1.toString() is another, so the == comparison returns false. (These are not literals in the pool.)

Of course, the deeper equals() comparison returns true.

Same code without the redundant if stuff:


Prints "falsefalse" on Java 1.5.
