I'm struggling with figuring out the bug in this code it says that my first and last curly brace are wrong but they need to be there?
import java.util.InputMismatchException; 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; //variable to exit the loop boolean endLoop = true; final double squareFeetPerGallons = 350.0; // Implement a do-while loop to ensure input is valid // Prompt user to input wall's height do { try { System.out.println("Enter wall height (feet): "); wallHeight = scnr.nextDouble(); System.out.println("Enter wall width (feet): "); wallWidth = scnr.nextDouble(); //make statements to correct invalid inputs if((wallHeight <= 0) && (wallWidth <= 0)) { throw new Exception(" Invalid height and width. Numbers must be greater than 0. "); } else if(wallHeight <= 0) { throw new Exception(" Invalid height. Height must be greater than 0. "); } else if(wallWidth <= 0) { throw new Exception(" Invalid width. Width must be greater than 0. "); } else { endLoop = false; } } //if not int or float catch(InputMismatchException excpt) { System.out.println(" Expected a number as input. "); scnr.nextLine(); } catch (Exception excpt) { System.out.println(excpt.getMessage()); scnr.nextLine(); } while(endLoop);
// Implement a do-while loop to ensure input is valid // Prompt user to input wall's width
// Calculate and output wall area wallArea = wallHeight * wallWidth; System.out.println("Wall area: " + wallArea + " 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");
