I used to use the >> operator for right shifting. Now I’ve just replaced it with >>> and found the same result. So I can’t figure out whether these two are fundamentally equal or not.

The first operator sign-extends the value, shifting in a copy of the sign bit; the second one always shifts in a zero.
The reason for this is to emulate unsigned integers for the purpose of doing bit operations, partially compensating for the lack of unsigned integral types in Java.
