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.");
 }
}

Output of program:


Another method to check odd or even

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.

import java.util.Scanner;
public class EvenOrOdd { 
public static void main(String args[]) { 
Scanner obj = new Scanner(System.in);
int no;
System.out.println("Enter any number to check if it is Even or Odd number:");
no = obj.nextInt();
isOddOrEven(no); 
}
public static void isOddOrEven(int number){ 
if((number & 1) == 0){ 
System.out.println("Using bitwise operator: " + number + " is Even number"); 
}
else{ 
System.out.println("Using bitwise operator: " + number + " is Odd number"); 
} 
} 
}
