Question

This paint class needs to implement a do-while loop for valid input. A try and catch i would like to know how to

implement into this class in addition.


import java.util.Scanner;


public class Paint1 {


  public static void main(String[] args) {

    Scanner scnr = new Scanner(System.in);

    double wallHeight = 0.0;

    double wallWidth = 0.0;

    double wallArea = 0.0;

    double gallonsPaintNeeded = 0.0;

     

    final double squareFeetPerGallons = 350.0;

     

    // Implement a do-while loop to ensure input is valid

    // Prompt user to input wall's height

    System.out.println("Enter wall height (feet): ");

    wallHeight = scnr.nextDouble();


    // Implement a do-while loop to ensure input is valid

    // Prompt user to input wall's width

    System.out.println("Enter wall width (feet): ");

    wallHeight = scnr.nextDouble();


    // Calculate and output wall area

    wallArea = wallHeight * wallWidth;

    System.out.println("Wall area: square feet");


    // Calculate and output the amount of paint (in gallons) needed to paint the wall

    gallonsPaintNeeded = wallArea/squareFeetPerGallons;

    System.out.println("Paint needed: " + gallonsPaintNeeded + " gallons");


  }

}
