JAVA program 1

Design a program for the Hollywood Movie Rating Guide, which can be installed in a kiosk in theaters.

Each theater patron enters a value from 0 to 4 indicating the number of stars that the patron awards to the Guide’s featured movie of the week.

If a user enters a star value that does not fall in the correct range, re-prompt the user continuously until a correct value is entered.

The user gets three tries to enter a valid rating. After three incorrect entries, the program issues an appropriate message and continues with a new user.

The program executes continuously until the theater manager enters a negative number to quit. When the manager enters the negative number end of the program, display the average star rating for the movie.

I can write the pseudocode but cannot make it work in JAVA.

Pseudocode:

start
        Declarations
            num numOfStars
            num count = 0
            num total = 0
            num attempts
            num avg
            num LIMIT = 3
            string PROMPT = "Enter the star rating or a negative number to quit >> "
        housekeeping()
        while numOfStars >= 0 AND attempts < LIMIT
            detailLoop()
        endwhile
        finishUp()
    stop
housekeeping()
    output PROMPT
    input numOfStars
    attempts = 0
return
detailLoop()
        while (numOfStars > 4 OR numOfStars < 0) AND attempts < LIMIT
            output "Please re-enter a value from 0 to 4 >> "
            input numOfStars
            attempts = attempts + 1
        endwhile
        if attempts < LIMIT then
            count = count + 1
            total = total + numOfStars
            output PROMPT
            input numOfStars
        else
            output "You have failed to enter a valid rating."
            output "The program will now end."
        endif
return
finishUp()
    if attempts < LIMIT then
        avg = total / count
        output "The average star rating is: ", avg
    endif
    output "End of program"
return

MovieRatingGuide.java

import java.util.Scanner;

public class MovieRatingGuide {

  private static Scanner in = new Scanner(System.in);
  private static final int LIMIT = 3;

  public static void main(String[] args) {

    // declarations
    int count = 0;
    int total = 0;

    String prompt = "Enter the star rating or a negative number to quit>> ";

    // house keeping
    int numOfStars = housekeeping();

    while (numOfStars >= 0) {
      numOfStars = detailLoop(numOfStars);
      if (numOfStars >= 0 && numOfStars <= 4) {
        count = count + 1;
        total = total + numOfStars;
      } else {
        System.out.println("You have failed to enter a valid rating.");
      }
      // for the next user to enter the rating
      System.out.print(prompt);
      numOfStars = in.nextInt();
    }

    // finish up
    finishUp(total, count);
  }

  private static int housekeeping() {
    String prompt = "Enter the star rating or a negative number to quit>> ";
    System.out.print(prompt);
    int numOfStars = in.nextInt();
    return numOfStars;
  }

  private static int detailLoop(int numOfStars) {
    String prompt = "Enter the star rating or a negative number to quit>> ";
    int attempts = 1;
    // detail loop
    while ((numOfStars > 4 || numOfStars < 0) && attempts < LIMIT) {
      System.out.print("Please re-enter a value from 0 to 4 >> ");
      numOfStars = in.nextInt();
      attempts = attempts + 1;
    }
    if (attempts < LIMIT) {
      return numOfStars;
    }
    // return -1 to indicate invalid value
    return -1;
  }

  private static void finishUp(int total, int count) {
    if (count > 0) {
      double average = total / count;
      System.out.println("The average star rating is: " + average);
    }
    System.out.println("End of program");
  }
}

You will find an example Java project, that demonstrates the style of the work we are able to do for you.

JAVA program 2

The Downdog Yoga Studio offers five types of classes, as shown in Table 6-2.

Design a program that accepts a number representing a class and the numeric class requests can be entered continuously until a sentinel value is entered.

Then, display each class number, name, and a count of the number of requests for each class.

Class Number	Class Name
1	Yoga 1
2	Yoga 2
3	Children’s Yoga
4	Prenatal Yoga
5	Senior Yoga

Table 6 – 2

I can write the pseudocode but cannot make it work in JAVA.

Pseudocode:

start
    Declarations
        num classNum
        num QUIT = -1
        num SIZE = 5
        num classCnt[SIZE] = 0
        string classes[SIZE] = "Yoga 1", "Yoga 2", 
                       "Children's Yoga", "Prenatal Yoga", 
                       "Senior Yoga"
    getReady()
    while classNum <> QUIT
        countClasses()
    endwhile
    finishUp()
stop

getReady()
    output "Enter a class number or ", QUIT, " to quit"
    input classNum
return
countClasses()
    if classNum >= 1 AND classNum <= SIZE then
        classCnt[classNum-1] = classCnt[classNum-1] + 1
    else
        output "Invalid class number"
    endif
    output "Enter a class number or ", QUIT, " to quit"
    input classNum
return
finishUp()  
    classNum = 0
    while classNum < SIZE
        output classNum+1, classes[classNum], classCnt[classNum]
        classNum = classNum + 1
    endwhile
return

YogaStudio.java

import java.util.Scanner;

Below is a Java project, but if you just require a Java online tutor then we can provide that for you as well.

JAVA program 3

Draw the hierarchy chart and design the logic for a program that calculates service charges for Hazel’s Housecleaning service.

The program contains housekeeping, detail loop, and end-of-job modules.

The main program declares any needed global variables and constants and calls the other modules.

The housekeeping module displays a prompt for and accepts a customer’s last name. While the user does not enter ZZZZ for the name, the detail loop accepts the number of bathrooms and the number of other rooms to be cleaned.

The service charge is computed as $40 plus $15 for each bathroom and $10 for each of the other rooms. The detail loop also displays the service charge and then prompts the user for the next customer’s name.

The end-of-job module, which executes after the user enters the sentinel value for the name, displays a message that indicates the program is complete.

Again I can write the pseudocode just can’t convert to JAVA.

Pseudocode:

start
        Declarations
            string customerLastName
            num numOfBaths
            num numOfOtherRooms
            num serviceCharge
            num CHARGE_BASE = 40
            num CHARGE_BATH = 15
            num CHARGE_OTHER_ROOM = 10
            string QUIT = "ZZZZ"
            string NAME_PROMPT = "Enter the customer's last name: " 
            string BATH_PROMPT = "Enter the number of bathrooms to be 
                            cleaned: "
            string ROOMS_PROMPT = "Enter the number of other rooms to 
                            be cleaned: "
        string END_LINE = "Thank you for using the program"
    housekeeping()
    while customerLastName <> QUIT
        detailLoop()
    endwhile
    endOfJob()
    stop
housekeeping()
    output NAME_PROMPT
    input customerLastName
return
detailLoop()
    output BATH_PROMPT
    input numOfBaths
    output ROOM_PROMPT
    input numOfOtherRooms
    serviceCharge = CHARGE_BASE + (CHARGE_BATH * numOfBaths) +
                (CHARGE_ROOM * numOfOtherRooms)
    output serviceCharge
    output NAME_PROMPT
    input customerLastName
return
endOfJob()
    output END_LINE
