2. First, you will debug the Paint1 class so that no errors remain and all calculations work correctly by completing the following: o Find and fix the three errors in the given code. o Use the following sample input values to test your program. If you have found and fixed all the errors, your output should exactly match the sample. Input: 30 25 Output: Wall area: 750.0 square feet Paint needed: 2.142857142857143 gallons Tip: When you run your program in Eclipse, it will prompt you to enter input in the Console window. If you cannot find this window, go to Window, then Show View, then Console. 3. Next, you will add loops to validate all user input and handle exceptions so that code passes all test cases by completing the following: o Review the code, looking for the two code blocks where user input is required. o Implement a do-while loop in both blocks of code to ensure that input is valid and any exceptions are handled. o Use the two following sample sets of input to test your program. Since these inputs are invalid, your program should respond to each by prompting the user to enter valid input. This should continue to loop until valid input is received. import java.util.Scanner; public class Paintl { } 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 gallons PaintNeeded = 0.0; } final double square Feet PerGallons = 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 gallons PaintNeeded = wallArea/square Feet PerGallons; System.out.println("Paint needed: " + gallonspaintneeded + " gallons");
