Multiplication Table

Write a Java program that takes a number as input and prints its multiplication table up to 10.

Test Data:
Input a number: 8

Pictorial Presentation:

Sample Solution:

Java Code:

import java.util.Scanner;
 
public class Exercise7 {
 
 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 a number
  System.out.print("Input a number: ");
  
  // Read and store the input number
  int num1 = in.nextInt();
   
  // Use a loop to calculate and print the multiplication table for the input number
  for (int i = 0; i < 10; i++) {
     // Calculate and print the result of num1 multiplied by (i+1)
     System.out.println(num1 + " x " + (i + 1) + " = " + (num1 * (i + 1)));
  }
 }
}

Explanation:

In the exercise above -

• It takes an integer number as input from the user using the Scanner class.
• It then enters a for loop that iterates 10 times (for values of i from 0 to 9).
• Inside the loop, it calculates and prints the result of multiplying the input number by i+1, displaying a multiplication table for the input number from 1 to 10.

Sample Output:

Input a number: 8                                                                                             
8 x 1 = 8                                                                                                     
8 x 2 = 16                                                                                                    
8 x 3 = 24                                                                                                    
8 x 4 = 32                                                                                                    
8 x 5 = 40                                                                                                    
8 x 6 = 48                                                                                                    
8 x 7 = 56                                                                                                    
8 x 8 = 64                                                                                                    
8 x 9 = 72                                                                                                    
8 x 10 = 80

Sample Solution:

Java Code:

import java.util.Scanner;

public class Main {

 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 a number
  System.out.println("Input the Number: ");
  
  // Read and store the input number
  int n = in.nextInt();
  
  // Use a loop to generate and print the multiplication table for the input number
  for (int i = 1; i <= 10; i++) {
     // Calculate and print the result of n multiplied by i
     System.out.println(n + "*" + i + " = " + (n * i));
  }
 }
}

Sample Output:

Input the Number: 
 6
6*1 = 6
6*2 = 12
6*3 = 18
6*4 = 24
6*5 = 30
6*6 = 36
6*7 = 42
6*8 = 48
6*9 = 54
6*10 = 60
