Write a Java program that generates the second, third, and fourth powers of a list of whole numbers from 1 to n where n is input by the user. Write a Java program to do this. • First, ask the user for the largest of the whole numbers to use (n). • Second, output column headers (see below, n, n^2, n^3, n^4). • Then, use a for loop to iterate from 1 to n, computing each of that loop variable to the second power, third power and fourth power, respectively. NB: The values should be stored in a 2dimensional array. Display the values as shown below: Sample output

//import the Scanner class

import java.util.Scanner;

//Begin class definition

public class Powers{

       //Begin the main method

    public static void main(String []args){

        //Create an object of the Scanner class

        //to allow for user inputs

       Scanner input = new Scanner(System.in);

        //Prompt the user to enter the largest of the whole number

       System.out.println("Enter the largest of the whole numbers to use");

        //Receive user input using the Scanner object

        //and store in an integer variable

       int n = input.nextInt();

       //Create a two-dimensional array using the user input

       int [][] powerlist = new int [n][4];

       //Create an outer for loop

       //to loop as many times as the number entered by the user

       for (int i = 0; i < n; i++){

           //Create an inner loop to find

           //the powers of each of the numbers

           for(int j = 0; j < 4; j++){

               //Typecast the value returned from the Math.pow() function

               powerlist[i][j] = (int) Math.pow((i+1), (j+1));

           }

       }

       //Print out the header of the table

       //\t will print a tab character.

      System.out.println("n" + "\t\t" + "n^2" + "\t\t" + "n^3" + "\t\t" + "n^4");

       //Print out the elements in the two dimensional array

      for (int i = 0; i < powerlist.length; i++){

          for(int j = 0; j < powerlist[i].length; j++){

               //Separate each term by two tabs

              System.out.print(powerlist[i][j] + "\t\t");

           }

           System.out.println();

       }

    }

}

Sample Output:

Enter the largest of the whole numbers to use

4

n  n^2  n^3  n^4

1  1  1  1  

2  4  8  16  

3  9  27  81  

4  16  64  256
