Program:

/*
 * Here we will see the effect of precedence in operators life
 */
public class OperatorAssociativityExample {

 public static void main(String args[]) {
 int i = 40;
 int j = 80;
 int k = 40;

 int l = i / k * 2 + j;
 /*
 * In above calculation we are not using any bracket. And there are two
 * operator of same precedence(divion and multiplication) so which
 * operator(/ or *) will be evaluated first is decided by association.
 * Associativity of * & / is left to right. So divison will be evaluated
 * first then multiplication.
 *
 * So the output will be 82.
 */

 System.out.println("value of L :" + l);

 int m = i / (k * 2) + j;
 /*
 * In above calculation brackets are used so associativity will not come
 * in picture and multiply(*) will be evaluated first and then
 * divison()/. So output will be 80
 */

 System.out.println("Value of M:" + m);
 }

}

Output:

value of L :82
Value of M:80
