/*
* 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);
}
}
value of L :82
Value of M:80

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
