Java program to find odd or even

This java program finds if a number is odd or even. If the number is divisible by 2 then it will be even, otherwise it is odd. We use modulus operator to find remainder in our program.

Java programming source code

import java.util.Scanner;
 
class OddOrEven
{
public static void main(String args[])
{
int x;
System.out.println("Enter an integer to check if it is odd or even ");
Scanner in = new Scanner(System.in);
x = in.nextInt();
 
if ( x % 2 == 0 )
System.out.println("You entered an even number.");
else
System.out.println("You entered an odd number.");
}
}
Download Odd or even program class file.
Output of program:
odd even
Another method to check odd or even, for explanation see: c program to check odd or even. Code:
import java.util.Scanner;
 
class EvenOdd
{
public static void main(String args[])
{
int c;
System.out.println("Input an integer");
Scanner in = new Scanner(System.in);
c = in.nextInt();
 
if ( (c/2)*2 == c )
System.out.println("Even");
else
System.out.println("Odd");
}
}
There are other methods for checking odd/even one such method is using bitwise operator.
