Implement a class named Rectangle to represent a rectangle using Java
1) Class name: Rectangle; accessibility: public
2) The class contains: Two private double data fields named width and height that specify the width and height of the rectangle.
3) A no-arg constructor that creates a default rectangle: data fields are 1 for both width and height.
4) A constructor that creates a rectangle with the specified width and height.
5) A public method named setWidth that sets the value of width
6) A public method named getWidth that returns the value of width
7) A public method named setHeight that sets the value of height
8) A public method named getHeight that returns the value of height
9) A public method named getPerimeter() that returns the perimeter.
10) A public method named getArea() that returns the area of this rectangle.
11) Draw the UML class diagram
12) Write a test file that creates two Rectangle objects: one with width 4 and height 40 and the other with width 3.5 and height 35.9. Display the width, height, area and perimeter of each rectangle in this order

Elevator uses a constructor to initialize the number of floors (N) in the building when the object is instantiated. Elevator also has a default constructor that creates a five- (5) storey building. The Elevator class has a termination condition that requires the elevator to be moved to the main (i.e., first) floor when the object is cleaned up. Write a finalize() method that satisfies this termination condition and verifies the condition by printing a message to the output, Elevator ending: elevator returned to the first floor. In main(), test at least five (5) possible scenarios that can occur when Elevator is used in a building with many floors (e.g., create, move from one floor to another, etc.). Hint: Termination occurs when the instance is set to null. You may wish to investigate “garbage collection” for this exercise. When solving this problem make sure that the user can interact with the…arrow_forward

CODE IN PYTHON Create a BankAccount class which has an __init__ method which accepts an account name and starting balance to store as instance fields. The class should also have a method to deposit money, a method to withdraw money, and a method called "get_balance" which returns a string of the format "{account_name} has a balance of {balance}" (do not print this out from within the class, just return the string). In the same file, create an instance of the BankAccount class with a hardcoded name and starting balance. Deposit any amount to the account and withdraw any amount from the account (both can be hardcoded) and then print the result of calling the get_balance method on the instance.arrow_forwardWrite a Java class named PhoneRecord.java that performs the following functions: The class should contain the following data attributes and methods: private String name - The customer's name private String number - The customer's phone number public PhoneRecord(String personName, String phoneNumber) - Constructor get/set Methods - For each data attribute public String toString( ) - Special method to be used when printing a phoneRecord object Thank you so much for your help.

- 1. Create a properly encapsulated class named Person that has the following: A String instance variable called name. A constructor that takes a String parameter and sets the instance variable. A properly named getter for the instance variable. A correctly overrided equals method which returns true if the name instance variable of the parameter and the reference variable calling the method are equal. (Do not forget the null and class type checks!) Compile your Person class. 2. Create a properly encapsulated class named Employee that inherits from Person and has the following: ● ● ● A String instance variable called office (e.g. "LWH 2222"). A String instance variable called hourlywage (e.g. "$45.15").

Include both a constructor without any parameters and one with parameters for the description (String), cost (double) and weight (double) (in that order). For the constructor without parameters, set the description to an empty string, the cost to 0.0 and the weight to 0.0. Include appropriate accessor and mutator methods (and label them with comments including the terms "accessor" or "mutator"). So that the test cases compile, name the accessor methods: getDescription() getCost() getWeight() Additionally, name the mutator methods:…arrow_forward1. Design a new Triangle class that extends the abstract GeometricObject class. Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filled.

The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not.arrow_forward
