How to Print Table in Java?

In this section, we will understand the logic to print tables and also implement that logic in Java programs.

A table (or multiplication table) is a sequence of numbers that are generated using multiplication. We enter an integer as input of which we want to print the table. After that, we multiply the entered number by 1 to 10, respectively on by one.

Suppose, we have entered 5 as input then the table of 5 will be:

5*1 = 5
5*2 = 10
5*3 = 15
------------
------------
5*8 = 40
5*9 = 45
5*10 = 50

We observe that the entered number is fixed and a variable is changing at each iteration. Let's implement the above logic in a Java program.

Printing Table in Java

There are many ways to print table in Java that are as follows:

Using Java for Loop
Using Java while Loop

Using Java for Loop

In the following program, we have entered a number whose table is to be print. After that, we have used a for loop that starts from 1 and executes till the condition i<=10 becomes false. Inside the for loop, we have performed the multiplication and print the same.

TableExample.java

import java.util.Scanner;
public class TableExample
{
public static void main(String args[]) 
{
Scanner sc = new Scanner(System.in);
System.out.print("Enter number: ");     
//reading a number whose table is to be print
int num=sc.nextInt();
//loop start execution form and execute until the condition i<=10 becomes false
for(int i=1; i <= 10; i++)
{
//prints table of the entered number    
System.out.println(num+" * "+i+" = "+num*i);
}
}
}

Output:

Using Java while Loop

The logic to print the table is the same as we have used in the previous program. But in the following program, we have used Java while loop in place of a for loop.

PrintTable.java

import java.util.Scanner;
public class PrintTable 
{
public static void main(String args[])
{
// number n for which we have to print the
// multiplication table.
Scanner sc = new Scanner(System.in);
System.out.print("Enter number: ");     
//reading a number whose table is to be print
int num=sc.nextInt();
System.out.print("Enter range: ");     
//reading a number whose table is to be print
int range=sc.nextInt();
int i = 1;
//while loop starts from 1 and execute up to the range 
while (i <= range) 
{
//prints table of the entered number up to the range
System.out.println(num + " * " + i + " = "+ num * i);
//increments the value of i by 1
i++;
}
}
}

Output:
