- In previous chapters, you have created programs for the Greenville Idol competition. Now create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing Dancing, Musical instrument, and Other. The class contains an auto-implemented property that holds a contestants name. The class contains fields for a talent code and description. The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue program so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this years competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value is entered. The expected revenue is calculated and displayed. The revenue is $25 per contestant. The program prompts the user for names and talent codes for each contestant entered. Along with the prompt for a talent code, display a list of the valid categories. After data entry is complete, the program displays the valid talent categories and then continuously prompts the user for talent codes and displays the names of all contestants in the category. Appropriate messages are displayed if the entered code is not a character or a valid code.arrow_forwardWrite a program named DemoJobs for Harolds Home Services. The program should instantiate several Job objects and demonstrate their methods. The Job class contains four data fields—description (for example, wash windows), time in hours to complete (for example, 3.5), per-hour rate charged (for example, $25.00), and total fee (hourly rate times hours). Include properties to get and set each field except the total fee—that field will be read-only, and its value is calculated each time either the hourly fee or the number of hours is set. Overload the + operator so that two Jobs can be added. The sum of two Jobs is a new Job containing the descriptions of both original Jobs (joined by and), the sum of the time in hours for the original Jobs, and the average of the hourly rate for the original Jobs. Harold has realized that his method for computing the fee for combined jobs is not fair. For example, consider the following: His fee for painting a house is $100 per hour. If a job takes 10 hours, he earns $1000. His fee for dog walking is $10 per hour. If a job takes 1 hour, he earns $10. If he combines the two jobs and works a total of 11 hours, he earns only the average rate of $55 per hour, or $605. Devise an improved, weighted method for calculating Harolds fees for combined Jobs and include it in the overloaded operator+() method. Write a program named DemoJobs2 that demonstrates all the methods in the class work correctly.arrow_forwardWrite a class named Employee that has the following fields: name: The name field is a String object that holds the employee's name. idNumber: The idNumber is an integer variable that holds the employee's ID number. department: The department field is a String object that holds the name of the department where the employee works. position: The position field is a String object that holds the employee's job title. Write mutator methods that store values in these fields and accessor methods that return the values in these fields. Once you have written the class, write a separate program that creates three Employee objects to hold the following data. Name ID Number Azah Samsudin Mira Kamal Che Yah Sam Department Computer Science Biomedical Language Position Programmer Researcher Lecturer 11011 35125 80001 The program should store the data in the three objects and then display the data for each employee on the screen.arrow_forward
- Convert the pseudocode into Python. 1. Pet ClassDesign a class named Pet, which should have the following fields:■ name: The name field holds the name of a pet.■ type: The type field holds the type of animal that a pet is. Example values are "Dog", "Cat", and "Bird".■ age: The age field holds the pet’s age.2. The Pet class should also have the following methods:■ setName: The setName method stores a value in the name field.■ setType: The setType method stores a value in the type field.■ setAge: The setAge method stores a value in the age field.■ getName: The getName method returns the value of the name field.■ getType: The getType method returns the value of the type field.■ getAge: The getAge method returns the value of the age field.3. Once you have designed the class, design a program that creates an object of the class and prompts the user to enter the name, type, and age of his or her pet. This data should be stored in the object. Use the…arrow_forwardAttached you will find a Java class called Employee. This class includes a constructor which sets name to blanks and salary to $0.00 and a constructor which sets name to a starting name and salary to a set amount. Additionally, the class includes methods to set the name and salary and return the name and salary. You will create a new class called Manager that inherits from the attached class Employee. Add a field named department of type String. Create a get and set method for the department variable. Supply a method toString that prints the manager's name, department, and salary. But you may not change anything in the Employee class. You will then create a test class that uses the Manager class. The test class should prompt the user to enter name, department and salary. This information should be stored in an array. Upon entry of an employee records, the program should output the information you entered.arrow_forwardMick’s Wicks makes candles in various sizes. Create a class for the business named Candle that contains the following data fields: color - of type String height - of type int price - of type double Create get methods for all three fields. Create set methods for color and height, but not for price. Instead, when height is set, determine the price as $2 per inch. Create a child class named ScentedCandle that contains an additional data field named scent (of type String) and methods to get and set it. In the child class, override the parent’s setHeight() method to set the price of a ScentedCandle object at $3 per inch.arrow_forward

- Create an car class that will be used by a car shop to keep track of inventory. The following attributes should be present in your automobile class: -private string make-private string model-private string color-private int year-private int mileage. The program should have methods such as: -default constructor-parameterized constructor-add a new vehicle method-list vehicle information (return string array)-remove a vehicle method-update vehicle attributes method. All methods should include try..catch constructs. Except as noted all methods should return a success or failure message (failure message defined in "catch"). 1. Create an additional class to call your automobile class (e.g., Main or AutomobileInventory). Include a try..catch construct and print it to the console. 2.
