Java Tutorial: Associativity of Operators in Java

Associativity

Associativity tells the direction of the execution of operators. It can either be left to right or vice versa.

/ * -> L to R

+ - -> L to R

++, = -> R to L

Here is the precedence and associativity table which makes it easy for you to understand these topics better:

Quick Quiz: How will you write the following expression in Java?

Code:

package com.company;

public class op_pre {
    public static void main(String[] args) {
        // Precedence & Associativity

        //int a = 6*5-34/2;
        /*
        Highest precedence goes to * and /. They are then evaluated on the basis
        of left to right associativity
            =30-34/2
            =30-17
            =13
         */
        //int b = 60/5-34*2;
        /*
            = 12-34*2
            =12-68
            =-56
         */

        //System.out.println(a);
        //System.out.println(b);

        // Quick Quiz
        int x =6;
        int y = 1;
        //  int k = x * y/2;

        int b = 0;
        int c = 0;
        int a = 10;
        int k = b*b - (4*a*c)/(2*a);
        System.out.println(k);

    }
}
