How do I Create a simple multiplication table application using java? The application will prompt the user for the multiplication table width. (values 3-10 are valid) For example, if they enter 10 the output would be: Enter table width > 10Enter table width > 10 Precede each entry with a 0 if the digit is less than two characters long as shown above. During your testing you can see what happens when you enter a width too large. Keep it between 3 and 10. This what I have import java.util.Scanner;public class MultiplicationTable {public static void main(String[] args) {Scanner input = new Scanner(System.in);String numChoiceString;int numChoice;System.out.println("Enter table width > ");numChoiceString = input.next();numChoice = Integer.parseInt(numChoiceString);System.out.print("*********MULTIPLICATION TABLE********* \n");for(int i=1; i <= 10; i++){ for(int j=1; j <= 10; j++){System.out.print(i*j+"\t");}System.out.println();}}}
