Java Check if integer is multiple of a number

Question

How do I check if a Java integer is a multiple of another number   For example  if int j is a multiple of 4

User · Answer

If I understand correctly  you can use the module operator for this  For example  in Java  and a lot of other languages   you could do     j is a multiple of four if j   4    0   The module operator performs division and gives you the remainder

More Efficiently public class Multiples       public static void main String  args             int j   5           System out println j   4    0

Use the remainder operator  also known as the modulo operator  which returns the remainder of the division and check if it is zero   if  j   4    0            j is an exact multiple of 4

User · Answer

Use modulo  whenever a number x is a multiple of some number y  then always x   y equal to 0  which can be used as a check  So use  if  j   4    0
