Is there a signed zero Integer in Java?

Question

I\'ve learned that floating point number s have a signed zero in java. But I\'m afraid Integer has not:

new Integer(\"0\").equals(new Integer(\"-0\"         


        

Answer 1

You cannot store a sign with Java integer primitive type.

Negative zero is an artifact of IEEE-754 representation, which stores a sign in a separate bit. Integers, on the other hand, are stored in two's complement representation, which has a unique representation for zero.
