Answer to Question #268830 in Java | JSP | JSF for haku

Question

1. Squares

Looping random numbers and manipulating those values are fun, too! Why don't we try one that returns the square of an inputted number repeatedly until the user inputs 0? Let's do this!

 

Instructions:

Using a do...while() loop, continuously scan for random integers that will be inputted by the user and print out its square, separated in each line.

Once the inputted value is 0, it will still print out its square value but should then terminate the loop afterwards. Use this concept in making your loop condition.

Input

Multiple lines containing an integer.

6

Output

Multiple lines containing an integer.

Answer 1

import java.util.Scanner;


public class App {


	/**
	 * The start point of the program
	 * 
	 * @param args
	 */
	public static void main(String[] args) {
		Scanner keyBoard = new Scanner(System.in);
		int numbers[] = new int[1000];
		int i = 0;
		int number = 1;
		do {
			number = keyBoard.nextInt();
			numbers[i] = number;
			i++;
		} while (number != 0);
		i = 0;
		do {
			number = numbers[i];
			System.out.println((number * number));
			i++;
		} while (number != 0);


		keyBoard.close();


	}
