Question

Your little sister asks you to help her with her multiplication, and you decide to write a Java program that tests her skills. The program will let her input a starting number, such as 5. It will generate ten multiplication problems ranging from 5 *1 to 5*10. For each problem she will be prompted to enter the correct answer. The program should check her answer and should not let her advance to the next question until the correct answer is given to the current question.

After testing ten multiplication problems, your program should ask whether she would like to try another starting number. If yes, your program should generate another corresponding ten multiplication problems. This procedure should repeat until she indicates no.

Answer 1

input code:

output:

code:

import java.util.*;
public class Main
{
   public static void main(String[] args)
   {
   char ch;  
   /*use do while loop so user can run untill he want*/
   System.out.print(" Multiplication table \n");
       do
       {
       /*make Scanner class Object*/
       Scanner sc=new Scanner(System.in);
       /*take tablenumber input*/
       System.out.print("Enter the table number : ");
       int n=sc.nextInt();
       /*print the table and take result from user*/
       for(int i=1;i<=10;i++)
       {
       int result=n*i,input;
       System.out.println(" "+n+" * "+i+"= ?");
       /*use do while loop so we take answer from user untill user enters the correct input*/
       do
       {
       System.out.print("----->Please enter the answer:");
       input=sc.nextInt();
       /*if answer is wrong than print wrong answer*/
       if(result!=input)
       {
       System.out.print("-----Wrong Answer Please Try again-----\n");
       }
       }while(input!=result);
       }
       /*ask user run again or not*/
       System.out.print("Want to run again(y/n) : ");
       ch=sc.next().charAt(0);
       }while(ch=='y'||ch=='Y');
   }
}
