Question 1 Create a class Apartment. The class has the following instance variables, constructor, and methods. • A String instance variable m_city. • An int instance variable m numBedRooms. • An int instance variable m numBathRooms. • A double instance variable m monthlyRent. • A constructor that takes four parameters and sets the values of the instance variables accordingly. • A method displayApartment() that takes no parameter and returns nothing. The method displays the information of the apartment in a format of your design. Build a test driver by creating a class TestApartment to test the functionality of the class Apartment.

1- Design a class named Rectangle to represent a Rectangle. The class contains: • three variables integer data field named height, integer data filed named width and integer data filed named length. The default values are 1 for height, length, and width are 1.0 for each of them respectively. • A no-arg constructor that creates a default Rectangle. • A constructor that creates a Rectangle with the specified height, length and width. • A method named getVolume() that returns the volume of this Rectangle. (Volume = height * width * length) %3! 2- Write a test program called Test Rectangle that: • Creates two Rectangle objects: one object with height 11, length 5, and width 7, the other object with height 10, length 2 and width 6 • Display the volume of each Rectangle object.

1. Create a class as described below: Class Name: Room Fields: standard room fee amenities total cost Constructors:A default constructor to initialize the fields. The standard room fee field should be set to $200 and the amenities field to zero. Another constructor with one argument. It should assign this value to the standard room fee and the amenities field to the default value of $75. Methods: getStandardFee() - This methods returns the standard room fee field value. getAmenities() - This method returns the amenities field value. getTotalCost() - This method returns the total cost field value. calcTotalCost() - This method calculated the total cost for an instance of the class setStandard Fee() - This method has one argument representing the standard room fee. setAmenities() - This method has one argument representing the amenities for the room.

Describe the class's private and public components.

For your homework assignment, build a simple application for use by a local retail store. Your program should have the following classes: Item: Represents an item a customer might buy at the store. It should have two attributes: a String for the item description and a float for the price. This class should also override the __str__ method in a nicely formatted way. Customer: Represents a customer at the store. It should have three attributes: a String for the customer's name, a Boolean for the customer's preferred status, and a list of 5 indexes to hold Item objects. Include the following methods: make_purchase: accepts a String and a double as parameters to represent the name and price of an item this customer is purchasing. Create a new Item object with this info and append it to the internal list. If the customer is a preferred customer based on the Boolean attribute's value, take 10% off the total sale price. __str__: Override this method to print the customer's name and every…

Create a class of Dog, some of the differences you might have listed out maybe breed, age, size, color, etc.    Then create characteristics (breed, age, size, color) can form a data member for your object.   Then list out the common behaviors of these dogs like sleep, sit, eat, etc. Design the class dogs with objects and methods.

The class contains one constructor: public Account (double initBal, String owner, long number) which initializes the instance variables.   1. Overload the constructor as follows: public Account (double initBal, String owner) - initializes the balance and owner as specified; randomly generates the account number. public Account (String owner) - initializes the owner as specified; sets the initial balance to 0 and randomly generates the account number. public Account () - initializes the owner with empty string name; sets the initial balance to 0 and randomly generates the account number.   2. Overload the withdraw method that also takes a fee parameter and deducts that fee from the account.   3. Write a driver program that invokes all four versions of the constructors and two versions of the withdraw methods. Think about how the compiler can tell which method is invoked.     Code:  //*******************************************************// Account.java//// A bank account class…
