Java Operator	Operator Description
[ ]	Array index
()	Method call
.	Member access
++	Prefix or postfix increment
--	Prefix or postfix decrement
+ -	Unary plus, minus
~	Bitwise NOT
!	Boolean (logical) NOT
(type)	Type cast
new	Object creation
* / %	Multiplication, division, remainder
+ -	Addition, subtraction
+	String concatenation
<<	Signed bit shift left to right
>>	Signed bit shift right to left
>>>	Unsigned bit shift right to left
< <=	Less than, less than or equal to
> >=	Greater than, greater than or equal to
instanceof	Reference test
==	Equal to
!=	Not equal to
&	Bitwise AND
&	Boolean (logical) AND
^	Bitwise XOR
^	Boolean (logical) XOR
|	Bitwise OR
|	Boolean (logical) OR
&&	Boolean (logical) AND
||	Boolean (logical) OR
? :	Conditional
=	Assignment
*= /= += -= %= <<= >>= >>>= &= ^= |=	Combinated assignment (operation and assignment)

Java Operator Precedence

Java operator precedence is how Java determines which operator to evaluate first.

In this chart, operator precedence is displayed from highest precedence to lowest precedence.

Priority	Operator	Operation	Order of Evaluation
1	[ ]	Array index	Left to Right
	()	Method call
	.	Member access
2	++	Prefix or postfix increment	Right to Left
	--	Prefix or postfix decrement
	+ -	Unary plus, minus
	~	Bitwise NOT
	!	Boolean (logical) NOT
	(type)	Type cast
	new	Object creation
3	* / %	Multiplication, division, remainder	Left to Right
4	+ -	Addition, subtraction	Left to Right
	+	String concatenation
5	<<	Signed bit shift left to right	Left to Right
	>>	Signed bit shift right to left
	>>>	Unsigned bit shift right to left
6	< <=	Less than, less than or equal to	Left to Right
	> >=	Greater than, greater than or equal to
	instanceof	Reference test
7	==	Equal to	Left to Right
	!=	Not equal to
8	&	Bitwise AND	Left to Right
	&	Boolean (logical) AND
9	^	Bitwise XOR	Left to Right
	^	Boolean (logical) XOR
10	|	Bitwise OR	Left to Right
	|	Boolean (logical) OR
11	&&	Boolean (logical) AND	Left to Right
12	||	Boolean (logical) OR	Left to Right
13	? :	Conditional	Right to Left
14	=	Assignment	Right to Left
	*= /= += -= %= <<= >>= >>>= &= ^= |=	Combinated assignment (operation and assignment)

Notes

• Expressions inside parentheses are evaluated first
• Nested parentheses are evaluated from the innermost parentheses to the outermost parenthesis.
• Operators in the same row in the chart have equal precedence.
