Question

QUESTION 12

1. Write a program that would prompt the user to enter an integer. The program then would displays a table of squares and cubes from 1 to the value entered by the user. The program should prompt the user to continue if they wish. Name your class NumberPowers.java, add header and sample output as block comments and uploaded it to this link.

   Use these formulas for calculating squares and cubes are:

   • square = x * x
   • cube = x * x * x

   Assume that the user will enter a valid integer.

   The application should continue only if the user enters “y” or “Y” to continue.

   Sample Output

   Welcome to the Squares and Cubes table
   
   Enter an integer: 4
   
   Number Squared Cubed
   ====== ======= =====
   1 1 1
   2 4 8
   3 9 27
   4 16 64
   
   Continue? (y/n): y
   
   Enter an integer: 7
   
   Number Squared Cubed
   ====== ======= =====
   1 1 1
   2 4 8
   3 9 27
   4 16 64
   5 25 125
   6 36 216
   7 49 343
   
   Continue? (y/n): n
   
   
   

Answer 1

ANSWER:-

import java.util.*;

class NumberPowers
{
   public static void main (String[] args)
   {
       int n;
       char ch;
       System.out.println("Welcome to the Squares and Cubes table");
       Scanner sc=new Scanner(System.in);
       do
       {
       System.out.println("\nEnter a integer : 4");
       n=sc.nextInt();
       System.out.println("\nNumber Squared Cubed");
       System.out.println("====== ======= =====");
       for(int i=1;i<=n;i++)
       System.out.println(i+" "+i*i+" "+i*i*i);
       System.out.println("\nContinue?(y/n): n");
       ch=sc.next().charAt(0);
       }while(ch=='y' || ch=='Y');
   }
}

OUTPUT:-

Welcome to the Squares and Cubes table

Enter a integer : 4

Number Squared Cubed
====== ======= =====
1 1 1
2 4 8
3 9 27
4 16 64

Continue?(y/n): n
