Nataly_w [17]

Answer:

The program in Java is as follows:

import java.util.*;

import java.lang.Math;

public class Rooter{

public static void main(String[] args) {

    Scanner input = new Scanner(System.in);

 int start;

 System.out.print("Start: ");

 start = input.nextInt();

 while(start<=0){

     System.out.print("Number must be positive\nStart: ");

     start = input.nextInt();  }

 while(start>=0){

     System.out.println(Math.sqrt(start));

     start--;  }

}

}

Explanation:

This declares start as integer

 int start;

This prompts the user for input

 System.out.print("Start: ");

This gets input for start

 start = input.nextInt();

The following is repeated until the user input is valid i.e. positive

<em>  while(start<=0){</em>

<em>      System.out.print("Number must be positive\nStart: ");</em>

<em>      start = input.nextInt();  }</em>

The following while loop prints the square root of each number till 0

<em>  while(start>=0){</em>

<em>      System.out.println(Math.sqrt(start));</em>

<em>      start--;  }</em>
