Java program to find odd or even number using switch statements

Java program to find odd or even number using switch statements

In this tutorial, we will discuss the concept of the Java program to find odd or even number using switch statements.

In this post, we are going to learn how to find odd or even number using switch statements in Java programming language

when you divide a number by two and if the balance is zero, it is an even number.

when you divided a number by two and if the balance is one, it is an odd number.

 

Example of even number 2,4,6,8,…..

Example of odd number 1,3,5,7,…..

 

Here, we will use a modular operator to display odd or even number of the given number

if n%2==0 n is an even number

if n%2==1 n is an odd number

 

Java program to find odd or even number

Find the Even number – Standard method

The program will check and display the  even number from the given number using switch statements in Java

Program 1

//C program to check whether number is EVEN using switch
class CheckEvenOddSwitch{
public static void main (String args[]){
int num1=100;
//int num2=111;

switch(num1%2){//this will return 0
case 0:
    System.out.println(num1+" is an Even number");
    break;
case 1:
    System.out.println(num2+" is an Odd number");

}

}
}

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

100 is an Even number

 

Find the Odd number – Standard method

The program will check and display the  odd number from the given number using switch statements

Program 2

//C program to check whether number is ODD using switch
class CheckEvenOddSwitch{
public static void main (String args[]){
//int num1=100;
int num2=111;

switch(num2%2){//this will return 1
case 0:
    System.out.println(num1+" is a Even number");
    break;
case 1:
    System.out.println(num2+" is a Odd number");

}

}
}

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

111 is an Odd number

 

Find the odd or Even number – Entered by user

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 using switch statements

//C program to check whether number is EVEN or ODD using switch
import java.util.Scanner;
class CheckOddEvenswitch2{
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 num

switch(num%2){//this will return either 0 or 1
case 0:
    System.out.println(num+" is a Even number");
    break;
case 1:
    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: 23
23 is a odd number

Case 2

Enter the integer number: 30
30 is a even number

 

Approach

• The modular operator uses to find the modulus of the number dividing by 2.
• Switch statements return either 0 or 1.
• Then, check the case value with 0 or 1.
• if the case value is 0, the number will be even and case value 1, the number will be odd.
