A quick example program to create multiplication table in java using simple for loop and while loops.

1. Overview

In this article, you’ll learn how to generate and print multiplication table in java for a given number.

This can be done using for loop and while or do while loops.

Knowledge on the below topics is required to understand the examples in this post.

for loops

while and dowhile loops

2. Generate Multiplication Table Using For Loop

Simple example program to create multiplication of any given number with help of for loop.

package com.javaprogramto.programs;
 
public class MultiplicationTableForLoop {
 
    public static void main(String[] args) {
        int tableNumber = 10;
 
        System.out.println("Generating the table 10");
        // generating table 10
        for (int i = 1; i <= 10; i++) {
 
            System.out.format("%d * %d = %d \n", tableNumber, i, tableNumber * i);
 
        }
 
        // generating the 20 table.
        System.out.println("\nGenerating the table 20");
        int anotherTableNumber = 20;
        for (int i = 1; i <= 10; i++) {
 
            System.out.format("%d * %d = %d \n", anotherTableNumber, i, anotherTableNumber * i);
 
        }
 
    }
 
}

Output:

Generating the table 10
* 1 = 10
* 2 = 20
* 3 = 30
* 4 = 40
* 5 = 50
* 6 = 60
* 7 = 70
* 8 = 80
* 9 = 90
* 10 = 100
 
Generating the table 20
* 1 = 20
* 2 = 40
* 3 = 60
* 4 = 80
* 5 = 100
* 6 = 120
* 7 = 140
* 8 = 160
* 9 = 180
* 10 = 200

3. Generate Multiplication Table Using While Loop

Next examples is using while loop running from 1 to 10.

public class MultiplicationTableWhileLoop {
 
    public static void main(String[] args) {
        int tableNumber = 5;
 
        System.out.println("Generating the table 9");
        int tableStartIndex = 1;
        int tableEndIndex = 10;
        // generating table 10
        while (tableStartIndex <= tableEndIndex) {
 
            System.out.format("%d * %d = %d \n", tableNumber, tableStartIndex, tableNumber * tableStartIndex);
            tableStartIndex++;
        }
 
        // generating the 20 table.
        System.out.println("\nGenerating the table 18");
 
        // resetting the start and end index
        tableStartIndex = 1;
        tableEndIndex = 10;
        int anotherTableNumber = 18;
        while (tableStartIndex <= tableEndIndex) {
 
            System.out.format("%d * %d = %d \n", anotherTableNumber, tableStartIndex, tableNumber * tableStartIndex);
            tableStartIndex++;
        }
 
    }
 
}

Output:

Generating the table 9
* 1 = 5
* 2 = 10
* 3 = 15
* 4 = 20
* 5 = 25
* 6 = 30
* 7 = 35
* 8 = 40
* 9 = 45
* 10 = 50
 
Generating the table 18
* 1 = 5
* 2 = 10
* 3 = 15
* 4 = 20
* 5 = 25
* 6 = 30
* 7 = 35
* 8 = 40
* 9 = 45
* 10 = 50

4. Conclusion

In this short article, you’ve seen the easy engineering program to print the multiplication table in java with the help of for and while loops.
