Write a Java Program to print multiplication table for any number

Objective

Write a Java program to print multiplication table for any given number “N”. Given an integer “N” generate its multiples. Each multiple must be printed on a new line in the form: N x i = result.

Constraints

2 ≤ N ≤ 10

Java Program to print multiplication table

The following program shows how to generate multiples using for loop.

import java.io.*;
import java.math.*;
import java.security.*;
import java.text.*;
import java.util.*;
import java.util.concurrent.*;
import java.util.regex.*;


public class MultiplicationTableSolution {
    public static void main(String[] args) throws IOException {

        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));
        int N = Integer.parseInt(bufferedReader.readLine().trim());      
  
        if ( 2 <= N && N <= 10){
            
             for (int i=1; i<=10; i++){
                 int result = N*i;
                 System.out.println(N+" x "+i+" = "+result);
             }  
          
        }       
      bufferedReader.close();              
    } 

        
}

Sample Input

Output

2 x 1 = 2
2 x 2 = 4
2 x 3 = 6
2 x 4 = 8
2 x 5 = 10
2 x 6 = 12
2 x 7 = 14
2 x 8 = 16
2 x 9 = 18
2 x 10 = 20

Print multiples using While Loop

The following program prints multiples using while loop.

public class MultiplicationTableSolution {
    public static void main(String[] args) throws IOException {
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));

        int N = Integer.parseInt(bufferedReader.readLine().trim());
        
        if ( 2 <= N && N <= 20){
            int i=1;
            while(i <= 10)
            {
               System.out.printf("%d * %d = %d \n", N, i, N* i);
               i++;
            }
            
        }
        
      bufferedReader.close();              
    }
       

        
}

Input

Output

3 x 1 = 3
3 x 2 = 6
3 x 3 = 9
3 x 4 = 12
3 x 5 = 15
3 x 6 = 18
3 x 7 = 21
3 x 8 = 24
3 x 9 = 27
3 x 10 = 30
