First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "Rooter" (without the quotation marks) that does the following: 1) Gets a positive integer (i.e. any number greater than 0) called "start" from the user after outputting a meaningful prompt. 2) Include data validation to ensure the user provides a positive integer. If the validation is not passed, provide the user with suitable feedback and stay in the program to let the user try again until valid input is received. 3) Uses a while loop that finds and displays the square root of every number from "start" down through 0. As an example, if the user entered 8, you would find the square root of 8, then the square root of 7, and so on. NOTES: Print each square root on a separate line. Use the Math.sqrt(double a) method to find each square root and output the result as a float using four decimal positions. Thoughts Refer to Horstmann chapter 2 for details on formatting output values. Include multiple runs of this program using a variety of values for the "start" variable. Be sure to test your input validation code as well. Copy and paste all of your sample runs in your source code as a block comment at the bottom below the closing curly brace.
