(a && b) has the same value as (a & b), but with && the expression b is not executed if a is false. In Java there is also an operator &=.
a &= b is the same as a = a & b.
Question: Why isn't there an operator &&=, at least in Java. Is there some reason why I would not make sense to have it, or is it simply that no one cares or needs it?
