Write a Java Program to Print Multiplication Table using For Loop, and While Loop with example

Java Program to Print Multiplication Table using For Loop

This Java program for Multiplication table allows the user to enter any integer value, and prints the multiplication table from that number to 9 using For Loop.

// Java Program to Print Multiplication Table
import java.util.Scanner;

public class MultiplicationTable {
	private static Scanner sc;
	public static void main(String[] args) 
	{
		int number, i, j;
		sc = new Scanner(System.in);
		
		System.out.print(" Please Enter any Number : ");
		number = sc.nextInt();	

		for(i = number; i < 10; i++)
		{
			for(j = 1; j <= 10; j++)
			{
				System.out.println(i +"  *  " + j + "  =  " + i * j);
			}
			System.out.println("================");
		}
	}
}

ANALYSIS

Within this Java program for multiplication table, First For loop is to iterate from user entered value to 9. Next, we used Nested For Loop to iterate j from 1 to 10

User entered value: number  = 9

First For Loop – First Iteration: for(i = 9; i < 10; i++)
Condition is True. So, it will enter into second For Loop

Second For Loop – First Iteration: for(j = 1; 1 <= 10; 1++)
Condition is True. So, Statement inside the system.out.println will be printed.

Second For Loop – Second Iteration: for(j = 2; 2 <= 10; 2++)
Condition is True. So, Statement inside the system.out.println will be printed.

Second For Loop will repeat the process until j reaches to 11. Because, if j is 11, condition will fails so, it will exit from the second loop.

First For Loop – Second Iteration: for(i = 10; i < 10; i++)
Condition (10 < 10) Fails. So, it will exit from the First For Loop

Java Program to display Multiplication Table using While Loop

This program for Multiplication table in Java is same as above example but this time we are using the While Loop.

// Java Program to Print Multiplication Table
import java.util.Scanner;

public class MultiplicationTable1 {
	private static Scanner sc;
	public static void main(String[] args) 
	{
		int i, j;
		sc = new Scanner(System.in);
		
		System.out.print(" Please Enter any Number : ");
		i = sc.nextInt();	

		while(i < 10)
		{
			j = 1;
			while(j <= 10)
			{
				System.out.println(i +"  *  " + j + "  =  " + i * j);
				j++;
			}
			System.out.println("================");
			i++;
		}
	}
}

Java Program for Multiplication Table using Method

This program is same as first example but we separated the logic and placed it in the separate method.

// Java Program to Print Multiplication Table
import java.util.Scanner;

public class MultiplicationTable2 {
	private static Scanner sc;
	public static void main(String[] args) 
	{
		int number;
		sc = new Scanner(System.in);
		
		System.out.print(" Please Enter any Number : ");
		number = sc.nextInt();	

		MultiTable(number);
	}
	
	public static void MultiTable(int num)
	{
		int i, j;
		
		for(i = num; i < 10; i++)
		{
			for(j = 1; j <= 10; j++)
			{
				System.out.println(i +"  *  " + j + "  =  " + i * j);
			}
			System.out.println("================");
		}
	}
}
