Part A
Create a class named Apartment that holds an apartment number as aptNumber, number of bedrooms as bedrooms, number of baths as baths, and rent amount as rent.
Create a default constructor that accepts no arguments and an overloaded constructor that accepts values for each data field.
Also create a get method for each field.
Part B
Write an application called TestApartments that creates at least five Apartment objects. Then prompt a user to enter a minimum number of bedrooms required, a minimum number of baths required, and a maximum rent the user is willing to pay. Display data for all the Apartment objects that meet the user’s criteria or an appropriate message if no such apartments are available.
An example of the program is shown below:
Enter minimum number of bedrooms needed >> 2
Enter minimum number of bathrooms needed >> 1.5
Enter maximum rent willing to pay >> 1200

at least 2 bedrooms, at least 1.5 baths, and no more than…

Create a constructor for the Student class you created. The constructor should initialize each Student’s ID number to 9999, his or her points earned to 12, and credit hours to 3 (resulting in a grade point average of 4.0). Write a program that demonstrates that the constructor works by instantiating an object and displaying the initial values. Save the application as ShowStudent2.java.

- Write 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_forwardIn 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_forwardCreate an application class named LetterDemo that instantiates objects of two classes named Letter and CertifiedLetter and that demonstrates all their methods. The classes are used by a company to keep track of letters they mail to clients. The Letter class includes auto-implemented properties for the name of the recipient and the date mailed. Also, include a ToString() method that overrides the Object classs ToString() method and returns a string that contains the name of the class (using CetType and the Letters data field values. Create a child class named CertifiedLetter that includes an auto-implemented property that holds a tracking number for the letter.arrow_forward
