5 ways to check whether the given integer is Even or Odd in Java

In this tutorial, we will discuss the concept of 5 ways to check whether the given integer is Even or Odd in Java.

In this post, we are going to learn how to check a number is Even or Odd using various five ways in Java programming language

5 ways to check whether the given integer is Even or Odd

Using modulo operator(%)

Program 1

import java.util.Scanner;
class CheckOddEven1{
public static void main(String args[]){
    Scanner scan=new Scanner(System.in); //create a scanner object for input
System.out.print("Enter the integer number: ");

int num=scan.nextInt();//get input from the user for num1
//using modular operator

int rem=num%2;
if(rem==0){
  System.out.println(num+" is a Even number");
}else{
 System.out.println(num+" is a Odd number");
}
}
}

When the above code is executed, it produces the following results

Case 1

Enter the integer number: 32
32 is a Even number

Case 2

Enter the integer number: 13
13 is a odd number

This program allows the user to enter a number and then, the program will check and display the odd or even numbers from the given number(entered by the user) using modular operator

Using division operator(/)

Program 2

import java.util.Scanner;
class CheckOddEven2{
public static void main(String args[]){
    Scanner scan=new Scanner(System.in); //create a scanner object for input
System.out.print("Enter the integer number: ");

int num=scan.nextInt();//get input from the user for num1
//using divisional operator
if((num/2) * 2==num){
  System.out.println(num+" is a Even number");
}else{
 System.out.println(num+" is a Odd number");
}
}
}

When the above code is executed, it produces the following results

Case 1

Enter the integer number: 99
99 is a odd number

Case 2

Enter the integer number: 50
50 is a even number

This program allows the user to enter a number and then, the program will check and display the odd or even numbers from the given number(entered by the user) using division operator

Using betwise AND operator(&)

Program 3

import java.util.Scanner;
class CheckOddEven3{
public static void main(String args[]){
    Scanner scan=new Scanner(System.in); //create a scanner object for input
System.out.print("Enter the integer number: ");

int num=scan.nextInt();//get input from the user for num1
//using Betwise AND operator

if((num&1)==0){
  System.out.println(num+" is a Even number");
}else{
 System.out.println(num+" is a Odd number");
}
}
}

When the above code is executed, it produces the following results

Case 1

Enter the integer number: 67
67 is a odd number

Case 2

Enter the integer number: 44
44 is a even number

This program allows the user to enter a number and then, the program will check and display the odd or even numbers from the given number(entered by the user) using bitwise AND operator

Using Left Shift and Right Shift operator(<<,>>)

Program 4

import java.util.Scanner;
class CheckOddEven4{
public static void main(String args[]){
    Scanner scan=new Scanner(System.in); //create a scanner object for input
System.out.print("Enter the integer number: ");

int num=scan.nextInt();//get input from the user for num1
//using shift operator

if(((num>>1)<<1)==num){
  System.out.println(num+" is a Even number");
}else{
 System.out.println(num+" is a Odd number");
}
}
}

When the above code is executed, it produces the following results

Case 1

Enter the integer number: 71
71 is a odd number

Case 2

Enter the integer number: 88
88 is a even number

This program allows the user to enter a number and then, the program will check and display the odd or even numbers from the given number(entered by the user) using shift operator

Using Ternary operator

Program 5

import java.util.Scanner;
class CheckOddEven5{
public static void main(String args[]){
    Scanner scan=new Scanner(System.in); //create a scanner object for input
System.out.print("Enter the integer number: ");

int num=scan.nextInt();//get input from the user for num1
//using ternary operator

String evenOdd=(num%2==0) ? "even":"odd";
System.out.println(num + " is "+evenOdd);
}
}

When the above code is executed, it produces the following results

Case 1

Enter the integer number: 143
143 is odd

Case 2

Enter the integer number: 266
266 is even

This program allows the user to enter a number and then, the program will check and display the odd or even numbers from the given number(entered by the user) using ternary operator
