Program to Check Even or Odd Number in Java

WAP to Check Even or Odd Number in Java

Logical Steps:

To check the number is even or odd, follow these steps:
1. Take a number.
2. Check if the number is divisible by 2:
  - Use the modulus (%) operator to divide the number by 2.
  - If the remainder is 0, the number is even.
  - Otherwise, it is odd.
3. Use an if-else statement for the condition:
  - If the remainder is 0, print that the number is even.
  - Else, print that the number is odd.
4. Print the result.

Program:

Below is the simple program:

public class CheckEvenOddNo
{
    public static void main(String[] args)
    {
        int number = 31;

        // Check if the number is even or odd using conditional logic
        if(number % 2 == 0)
        {
            System.out.println(number + " is an even number.");
        }
        else
        {
            System.out.println(number + " is an odd number.");
        }
    }
}

Output:

31 is an odd number.

Below is the program by taking user input:

import java.util.Scanner;

public class CheckEvenOddNo
{
    public static void main(String[] args)
    {
        // Import Scanner Class to take user input
        Scanner scanner = new Scanner(System.in);

        // Take input from the user
        System.out.print("Enter a number: ");
        int number = scanner.nextInt();

        // Check if the number is even or odd using conditional logic
        if(number % 2 == 0)
        {
            System.out.println(number + " is an even number.");
        }
        else
        {
            System.out.println(number + " is an odd number.");
        }

        // Close the scanner to release resources
        scanner.close();
    }
}

Output:

Enter a number: 26
26 is an even number.

Program Explanation:

Import Scanner Class:
- The Scanner class is imported to take user input.
Declare a Variable:
- An integer variable (number) is declared to store the user’s input.
Take Input:
- The program prompts the user to enter an integer, and scanner.nextInt() reads the input and stores it in the number variable.
Comparison Logic:
- The if condition checks if number % 2 is equal to 0. If true, it means the number is divisible by 2 and is an even number.
- Otherwise, the number is odd.
Display the Result:
- The program prints a message to indicate whether the number is even or odd.
Close Scanner:
- The scanner.close() method is used to close the input stream and release resources.
