Java operators

Operators are special symbols that perform specific operations on operands, and then return a result. The following are the operators supported by the Java programming language:

A simple assignment operator

• =: A simple assignment operator

Arithmetic operators

• +: An additive operator (also used for string concatenation)

• -: The subtraction operator

• *: The multiplication operator

• /: The division operator

• %: The remainder operator

Unary operators

• +: Unary plus operator; indicates positive value

• -: Unary minus operator; negates an expression

• ++: Increment operator; increments a value by 1

• --: Decrement operator; decrements a value by 1

• !: Logical complement operator; inverts the value of a Boolean value

Equality and relational operators

• ==: Equals to

• !=: Not equal to

• >: Greater than

• >=: Greater than or equal to

• <: Less than

• <=: Less than or equal to

Conditional operators

• &&: Conditional AND operator

• ||: Conditional OR operator

• ?: Ternary operator

Type comparison operator

• instanceof: This compares an object to a specified type

Bitwise and bit shift operators

• ~: Unary bitwise complement

• <<: Signed left shift

• >>: Signed right shift

• >>>: Unsigned right shift

• &: Bitwise AND

• ^: Bitwise exclusive OR

• |: Bitwise inclusive OR

Operator precedence

The operators in the following table are listed according to the precedence order. Operators with higher precedence are evaluated before operators with relatively lower precedence. Operators on the same line have equal precedence.

Precedence	Name	Operators	Associativity
1	postfix	expr++ expr--	Right to Left
2	unary	++expr --expr +expr -expr ~ !	Right to Left
3	multiplicative	* / %	Left to Right
4	additive	+ -	Left to Right
5	shift	<< >> >>>	Left to Right
6	relational	< > <= >= instanceof	Left to Right
7	equality	== !=	Left to Right
8	bitwise AND	&	Left to Right
9	bitwise exclusive OR	^	Left to Right
10	bitwise inclusive OR	|	Left to Right
11	logical AND	&&	Left to Right
12	logical OR	||	Left to Right
13	ternary	? :	Right to Left
14	assignment	= += -= *= /= %= &= ^= |= <<= >>= >>>=	Right to Left
