If any number is exactly divisible by 2 then it’s an even number else it’s an odd number.
In this tutorial we’ll see how to check whether the provided number is even or odd number using Modulo(%).

Flowchart for odd even
Note
- The remainder calculated with
%(Modulo) on dividing by 2, will always be0for all even numbers. - Whereas the remainder on dividing by 2, will always be
1for all odd numbers.
Code
public class OddEven
{
public static void main(String[] args)
{
int a = 58147;
int rem = a % 2;
System.out.println("A : " + a);
System.out.println("Remainder : " + rem);
if( rem == 0)
{
System.out.println( a + " is an even number");
}
else
{
System.out.println( a + " is an odd number");
}
/*
Remainder after dividing by 2
12 % 2 -> 0
13 % 2 -> 1
14 % 2 -> 0
15 % 2 -> 1
16 % 2 -> 0
17 % 2 -> 1
18 % 2 -> 0
19 % 2 -> 1
20 % 2 -> 0
21 % 2 -> 1
22 % 2 -> 0
*/
}
}Output
58147 is an odd numberHappy 😄 coding
