Product of Two Numbers

Write a Java program that takes two numbers as input and displays the product of two numbers.

Test Data:
Input first number: 25
Input second number: 5

Pictorial Presentation:

Sample Solution-1

Java Code:

import java.util.Scanner;
 
public class Exercise5 {
 
 public static void main(String[] args) {
  // Create a Scanner object to read input from the user
  Scanner in = new Scanner(System.in);
   
  // Prompt the user to input the first number
  System.out.print("Input first number: ");
  // Read and store the first number
  int num1 = in.nextInt();
   
  // Prompt the user to input the second number
  System.out.print("Input second number: ");
  // Read and store the second number
   
  // Calculate the product of the two numbers and display the result
  System.out.println(num1 + " x " + num2 + " = " + num1 * num2);
 }
} 

Explanation:

The above Java code takes two integer numbers as input from the user, multiplies them, and then displays the result in the format "num1 x num2 = result." It uses the "Scanner" class to read user input and performs multiplication on the input values.

Sample Output:

Input first number: 25                                                                                        
Input second number: 5                                                                                        
25 x 5 = 125

Sample Solution-2

Java Code:

public class Main
{
  // Declare and initialize static variables x and y
  static int x = 25;
  static int y = 5;

  public static void main(String[] args)
  {
    // Calculate and print the product of x and y
    System.out.println(x * y);
  }
}

Sample Output:

125
