Answer 1

Java Program:

import java.util.Scanner;

public class Main
{
        public static void main(String[] args) {
            Scanner sc = new Scanner(System.in);
            System.out.print("Enter First Double Number : ");
                double x = sc.nextDouble();
                System.out.print("Enter Second Double Number : ");
                double y = sc.nextDouble();
                
                
                // (a.) Using Math class
                if (Math.abs(x) == Math.abs(y))
                {
                    System.out.println("\nBoth Numbers are equal using Math class");
                }
                else
                {
                    System.out.println("\nBoth Numbers are not equal using Math class");
                }
                
                // (b.) Without using Math class
                if (x == y)
                {
                    System.out.println("\nBoth Numbers are equal !!");
                }
                else
                {
                    System.out.println("\nBoth Numbers are not equal !!");
                }
        }
}

Output:

Thumbs Up Please !!!
