Operators

Table A.2.1 Assignment operators. x and y must be numeric or char types
except for “= ” ,which allows x and y also to be object references. In this case, x
must be of the same type of class or interface as y. If mixed floating-point and
integer types, the rules for mixed types in expressions apply.

Operator Description

Assignment operator:
x = y;
yisevaluated and x set to this value.
The value of x is then returned.

=

+= , -= , *= , /= , %=

Arithmetic operation and then assignment, e.g.
x+= y;
is equivalent to
x = x+y;

&= , | = , ^=

Bitwise operation and then assignment, e.g.
x&= y;
is equivalent to
x = x&y;

<<= , >>= , >>>= Shift operations and then assignment, e.g.

x <<= n;
is equivalent to
x = x << n;
