If a client initiates the SMTP communication using an EHLO (Extended Hello) command instead of the HELO command some additional SMTP commands are often available. They are often referred to as Extended SMTP (ESMTP) commands or SMTP service extensions. Every server can have its own set of extended SMTP commands.

Create a class named CarRental that contains fields that hold a renter's name, zip code, size of the car rented, daily rental fe
Anarel [89]

Answer:

Here is the corrected code: The screenshot of the program along with its output is attached. The comments are written with each line of the program for better understanding of the code.

CarRental.java

public class CarRental  {  //class name

//below are the data members name, zipcode, size, dFee, days and total

String name;  

int zipcode;

String size;

double dFee;

int days;

double total;  

public String getName()  {  //accessor method to get the name

return name; }

public int getZipcode()  { //accessor method to get the zipcode

return zipcode; }

public String getSize() {  //accessor method to get the size

return size; }

public int getDays() {  //accessor method to get the days

return days;  }

public CarRental(String size)  {  //constructor of CarRental class

if(size.charAt(0)=='e')  // checks if the first element (at 0th index) of size data member is e

     dFee = 29.99;  // sets the dFee to 29.99

  else if(size.charAt(0)=='m')  // checks if the first element (at 0th index) of size data member is m

     dFee = 38.99;  // sets the dFee to 38.99

  else   // checks if the first element (at 0th index) of size data member is f

     dFee =43.50;  // sets the dFee to 43.50

   }

public void calculateTotal(int days) {  //method calculateTotal of CarRental

total = dFee*days;  }  //computes the rental fee

public void print()   {  //method to display the total rental fee

System.out.println("Your rental total cost is: $" + total);  } }

Explanation:

LuxuryCarRental.java

import java.util.*;

public class LuxuryCarRental extends CarRental {  //class LuxuryCarRental that is derived from class CarRental

public LuxuryCarRental(String size, int days) {  // constructor of LuxuryCarRental

super(size);}   //used when a LuxuryCarRental class and CarRental  class has same data members i.e. size

public void calculateTotal() {  //overridden method

super.calculateTotal(days); // used because CarRental  and LuxuryCarRental class have same named method i.e.  calculateTotal

dFee = 79.99;  //sets the rental fee at $79.99 per day

total = dFee;  }  //sets total to rental fee value

public void print(){  //overridden method

   int chauffeur;  // to decide to include chauffeur

Scanner keyboard = new Scanner(System.in);  //used to take input from user

System.out.println("Do you want to add a chauffeur for $200? Enter 0 for"

+ " yes and 1 for no");  // prompts the user to respond to the option of including a chauffeur at $200 more per day

chauffeur = keyboard.nextInt();   //reads the input option of chauffeur from user

if(chauffeur==1)  //if user enters 1 which means user does not want to add a chauffeur

total = dFee;  //then set the value of dFee i.e.  $79.99  to total

else  //if user enters 0 which means user wants to add a chauffeur

total = dFee + 200;  //adds 200 to dFee value and assign the resultant value to total variable

System.out.println("Your rental total cost is: $" + total);  }  } //display the total rental fee

UseCarRental.java

import java.util.*;

public class UseCarRental{ //class name

public static void main(String[] args){ //start of main() function body

String name, size; // declare variables

int zipcode, days; //declare variables

Scanner keyboard = new Scanner(System.in); // to take input from user

System.out.println("Enter total days you plan on renting: "); //prompts user to enter total days of rent

days = keyboard.nextInt(); // reads value of days from user

System.out.println("Enter your name: "); //prompts user to enter name

name = keyboard.next(); //reads input name from user

System.out.println("Enter your billing zipcode: "); // prompts user to enter zipcode

zipcode = keyboard.nextInt(); //reads input zipcode from user

System.out.println("Enter the size of the car: "); // prompts user to enter the value of size

size = keyboard.next(); //reads input size from user

CarRental economy = new CarRental(size); //creates an object i.e. economy of class CarRental

economy.calculateTotal(days); //calls calculateTotal method of CarRental using instance economy

economy.print(); //calls print() method of CarRental using instance economy

LuxuryCarRental fullsize = new LuxuryCarRental(size, days);  //creates an object i.e. fullsize of class LuxuryCarRental

fullsize.calculateTotal();  //calls calculateTotal method of LuxuryCarRental using instance fullsize

fullsize.print(); }} //calls print() method of LuxuryCarRental using instance fullsize

Explanation:

import java.util.Random;

import java.util.Scanner;

public class MultiplicationQuestions {

   public static void main(String[] args) {

       Scanner scan = new Scanner(System.in);

       Random rand = new Random();

       int n1, n2, result, total = 0, correct = 0;

       char ch = 'y';

       while(ch == 'y'){

           n1 = 1 + rand.nextInt(9);

           n2 = 1 + rand.nextInt(9);

           System.out.print("What is "+n1+" * "+n2+" ? ");

           result = scan.nextInt();

           if(result==n1*n2){

               System.out.println("Correct. Nice work!");

               correct++;

           }

           else{

               System.out.println("Incorrect. The product is "+(n1*n2));

           }

           System.out.print("Want more questions y or n ? ");

           ch = scan.next().charAt(0);

           total++;

       }

       System.out.println("You scored "+correct+" out of "+total);

   }
