Can someone please help me create a pseudo code to my code and explanation to it

import java.util.Scanner;

public class Paint1 {

public static void main(String[] args) {

// create an object for scanner class Scanner scnr = new Scanner(System.in);

// declare the variables double wallHeight = 0.0;

double wallWidth = 0.0;

double wallArea = 0.0;

double gallonsPaintNeeded = 0.0;

// declare a final variable final double squareFeetPerGallons = 350.0;

// Implement a do-while loop to ensure input is valid do{ // try block try { // Prompt user to input wall's height System.out.println("Enter wall height (feet): "); wallHeight = scnr.nextDouble(); // check if the wallHeight is less than or 0 // then throw an exception if(wallHeight<=0) { // throw an exception throw new Exception(); } } // catch the exception catch(Exception e) { // print the invalid message System.out.println("Invalid input!!"); } }while(wallHeight<=0);

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

do{ // try block try { // Prompt user to input wall's width System.out.println("Enter wall width (feet): "); wallWidth = scnr.nextDouble(); // check if the wallWidth is 0 or less // then throw an exception if(wallWidth<=0) { // throw an exception throw new Exception(); } } // catch the exception catch(Exception e) { // print the invalid message System.out.println("Inavlid Input!!"); } }while(wallWidth<=0);

// Calculate and output wall area

wallArea = wallHeight * wallWidth;

// print the wall area 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;

// print the output paint needed System.out.println("Paint needed: " + gallonsPaintNeeded + " gallons");

}

}
