Last Minute Java Operator Priority and Associativity Tutorial

java operator priority and associativity

Java language has operators of all kinds namely Arithmetic Operators, Relational Operators, Logical Operators and Bitwise Operators. Different Java operators have got different precedence and associativity.

Operators operate on Operands or expressions or constants in general. Operators work with different types of data namely integers, real numbers, boolean values and character data.

Java Operator Priority or Precedence and Associativity of all Operators

Along with operators like Arithmetic, Relational, Logical and Bitwise, Java also provides operators like Parentheses ( ) which increase the priority of a small expression inside a big expression. Type casting operation (typecast) has also got a higher priority. Let us see how Java Operator Precedence affects the result of any algebraic expression.

Golden Point: Java Operator Priority or Precedence decides which operators need to be evaluated first. Java Operator associativity decides which operator to be evaluated if more than one operators have equal priority.

Java All Operator Priority List
Priority Operator (s) Associativity
1 [ ], ( ), DOT (.) Left to Right
2 ++, -- Postfix Right to Left
3 ++, -- (Prefix), ~, !, Unary Minus (-), Unary Plus(+), (typecast L2R)  Right to Left
4 *, /, % Arithemetic Left to Right
5 +, - Arithmetic Left to Right
6 <<, >>, >>> Bitwise Left to Right
7 >, >=, <, <= Relational Left to Right
8 ==, != Relational Left to Right
9 & Bitwise, Logical Left to Right
10 ^ Bitwise, Logical Left to Right
11 | Bitwise, Logical Left to Right
12 && Bitwise, Logical Left to Right
13 || Bitwise, Logical Left to Right
14 ?: Ternary Operator Right to Left
15 -> Arrow Operator Left to Right
15 =, op= (Compound Assignment) Right to Left

From the above Java operator priority table, it is understood that Postfix Increment and Postfix Decrement operators have got highest Priority or Precedence among all other operators. Equal to and Compound Assignment Operator have got the least priority among all other operators.
