Procedure

TASK 1: Checking if a number is even or odd

import java.util.Scanner;
public class EvenOddChecker {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print(“Enter a number: “);
int number = scanner.nextInt();

if (number % 2 == 0) {
System.out.println(number + “ is an even number.”);
} else {
System.out.println(number + “ is an odd number.”);

}
scanner.close();
}
}
Explanation:

This Java program, named EvenOddChecker, is designed to determine whether a given input number is even or
odd. Here’s how it works:
1 The program starts by importing the Scanner class from the java.util package. The Scanner class allows user
input from the console.
2 The EvenOddChecker class contains the main method, which is the entry point of the program.
3 Inside the main method:
• It creates a new Scanner object named scanner to read input from the console.

• It prompts the user to enter a number by displaying the message “Enter a number: “.
