Operators
An operator is a symbol that specifies the operation to be performed on an instance. The operator performs an operation on the operand and returns an instance of the result.

Priority
Operators have priorities. Expressions containing multiple operators are operated in the order determined by precedence and associativity.
The following is a list of operators. The smaller number is the higher priority.
Priority 1 | ||
() | x(y) | Method call operator |
new | new int() | new operator |
this | this | this operator |
[] | x[y] | Indexer operator |
Priority 2 | ||
. | x.y | Dot operator |
++ | x++ | Postfix ++ operator |
-- | x-- | Postfix -- operator |
Priority 3 | ||
+ | +x | Unary + operator |
- | -x | Unary - operator |
! | !x | Logical negation operator |
++ | ++x | Prefix ++ operator |
-- | --x | Prefix -- operator |
Priority 4 | ||
* | x * y | Multiplication operator |
/ | x / y | Division operator |
% | x % y | Modulo operator |
Priority 5 | ||
+ | x + y | Addition operator |
- | x - y | Subtraction operator |
Priority 6 | ||
< | x < y | Less than operator |
<= | x <= y | Less than or equal operator |
> | x > y | Greater than operator |
>= | x >= y | Greater than equal operator |
Priority 7 | ||
== | x == y | Value equality operator |
!= | x != y | Value inequality operator |
$$ | x $$ y | Reference equality operator |
!$ | x !$ y | Reference inequality operator |
Priority 8 | ||
& | x & y | Logical AND operator |
Priority 9 | ||
| | x | y | Logical OR operator |
Change priority
You can change the priority of operations by using parentheses. Expressions in parentheses are preferentially operated.
int i = (2 + 2) * 2; // 8
