What is Operator Precedence in Java ?

Here, in this page we will discuss about the operator Precedence in Java. Java provides quite a variety of operators which come in handy to the programmer for the manipulation of variables.

Operator Precedence is defined by how two operators are bind together and how they will be evaluated. Operator with more precedence will be evaluated first in an expression.

Java Operator Precedence

The operators in java are as follows:

For example x = 10 – 4 * 2, here the value of x will be 2 not 12 as * (Multiplication) has more precedence over -, so it will be evaluated first which gives 8, then 8 will be subtracted from 10 which gives our final answer 2.

Note Precedence and Associativity of the operators are given below and Higher number means higher precedence of the operator.

Precedence And Associativity in Java :

Precedence	Operator	Type	Associativity
15	() [] ·	Parentheses Array subscript Member selection	Left to Right
14	++ —	Unary post-increment Unary post-decrement	Left to Right
13	++ — + – ! ~ ( type )	Unary pre-increment Unary pre-decrement Unary plus Unary minus Unary logical negation Unary bitwise complement Unary type cast	Right to left
12	* / %	Multiplication Division Modulus	Left to right
11	+ –	Addition Subtraction	Left to right
10	<< >> >>>	Bitwise left shift Bitwise right shift with sign extension Bitwise right shift with zero extension	Left to right
9	< <= > >= instanceof	Relational less than Relational less than or equal Relational greater than Relational greater than or equal Type comparison (objects only)	Left to right
8	== !=	Relational is equal to Relational is not equal to	Left to right
7	&	Bitwise AND	Left to right
6	^	Bitwise exclusive OR	Left to right
5	\|	Bitwise inclusive OR	Left to right
4	&&	Logical AND	Left to right
3	\|\|	Logical OR	Left to right
2	? :	Ternary conditional	Right to left
1	= += -= *= /= %=	Assignment Addition assignment Subtraction assignment Multiplication assignment Division assignment Modulus assignment	Right to left

Example :

Run

import java.util.*;

public class Main{
    public static void main(String[] args){
        // Initializing the variables
        int a = 10;
        int b = 20;
        int c = 30;
        int d = 60;
        int e;

        //10 + 600
        e = a + b * c;          
        System.out.println(e);

        //30 * 30
        e = (a + b) * c;     
        System.out.println(e);

        //30 * 2        
        e = (a + b) * (d / c);  
        System.out.println(e);
    }
}

Output:

610
900
60

Explanation In the above Example of Operator precedence, We had taken different Integer type Variables and we are testing the precedence of different operators with the help of different Examples throughout the program.
