- Create a java class person with following data members. Age: SHOULD BE VISIBLE TO ALL CLASSES. Name: SHOULD BE VISIBLE ONLY INSIDE THE CLASS AND TO INHERITED (DERIVED) CLASSES OF PERSON. Derived a class student from Person and add one data member name of the school (That should be visible to all the classes in the application).Class: Square Create a class called "Square", which is inherited from“TwoDimensionShape” class. The "Square" class is used to calculate theArea and the Perimeter of square shapes when their side-length is given, or in contrast,finding the side-length of the square when the Area or the Perimeter of the square is given.The specifications of this class are below. Data Members (Attributes): All are private. sideLength: the sidelight (L) of the square. Methods/Operations/Getters/Setters: Default Constructor: when creating an object this constructor must set the side-length of the square by calling the method setSideLength(). Also, this constructor willcall the findArea() and the findPerimeter() in addition to summaryPrint() to calculateand print all needed information. User-Defined Constructor: when creating an object this constructor shouldfind the side-length of the square by calling the method findSquareSideLength()and pass the Area or the…You need 5 java classes and these include Netflix Class (Parent class of Movie and TVShow class) Movie Class TVShow Class Test/TestDriver Class Database Class Please read the questions carefully.

Each transaction is an instance of theTransaction class, which is defined as shown in Figure ■■ Modify the withdraw and deposit methods to add a transaction to thetransactions array list. Write a test program that creates an Account with annual interest rate 1.5%,balance 1000, id 1122, and name George. Deposit $30, $40, and $50 to theaccount and withdraw $5, $4, and $2 from the account.

The class contains:■■ Private data fields startTime and endTime with getter methods.■■ A no-arg constructor that initializes startTime with the current time.■■ A method named start() that resets the startTime to the current time.■■ A method named stop() that sets the endTime to the current time.■■ A method named getElapsedTime() that returns the elapsed time for thestopwatch in milliseconds.Draw the UML diagram for the class then implement the class. Write a test programthat measures the execution time of sorting 100,000 numbers using selection sort.
- Assignment - LocationsFor this assignment, we will be creating our location class and then a few locations to subclass from it. Most of these classes will be rather short so you can put them all in locations.py if you would likeCreate the Location classCreate the Town classCreate the Palace and Lumbermill classes Location ClassThe Location class establishes the basic properties of a location: manager - holds the character that manages the locationforeColor - holds the fore color of the locationbackColor - holds the back color of the locationEnter() - default method for entering a location. By default, the manager should greet you and all text displayed should use the foreColor and backColor of the location.Exit() - default method for leaving a location.
