1/3Part-1 (Objects and Classes)Create a Java Project (with a class and a test class) to represent some real-world entity such as atechnology item (TV. Fan etc), an animal, a person, a vehicle, etc. In our class, we have alreadyseen example classes such as Circle, Student, Rectangle, TV etc.The class will:a) Create a total of 5 member variables for the class by selecting the appropriate data typesfor each field. For example, a class to represent a lamp might include color, price, height,numBulbs, batteryOperated. Each of these 5 variables needs a data type.b) Include at least three different constructor methods, including the default constructor(no argument constructor), so totally three constructors.c) Create a method called showValues( ) to display the values of an object in a formattedmanner,The Java test class (with a main method) will:a) Instantiate at least three objects (using each of the constructors at least once) with yourprogram.b) Store the data from the individual objects into an array.c) Utilize the show Values(() method to display the content of an object created.Note:) Draw the UML diagram for the class and then implement the class. Draw object diagramswherever possible to show the state of the objects created2) Generate output samples demonstrating all of your member functions showing theirfunctionality (Le. inputting values, outputting values (displaying them), performingcaleulations, etc.).Include the below in your project report:1. The UML diagram of the class.2. The class and test class3. Sereenshots of output generated from the application.Fall 2020

Classes: Write a Person class that has these attributes: person_ID, first and last names, and age Default and overloaded constructors Accessors and mutators equals method toString method (make this virtual if C++, don't forget to prep the class for polymorphism) Inheritance: Create a child class to Person called Student: Attributes: GPA and status (freshman, sophomore, junior, senior, graduate, graduated). Make sure you have appropriate accessor/mutator methods Create another child class to represent Faculty. This class will have faculty rank and length of service as attributes along with an office location. Again, add methods as needed. Application Create an application that displays a menu that allows users to add students or faculty, or print either one or exit. Deliverable: Submit your source code and classes on Github (you will be supplied an account) You will also submit a Word document and your code on Canvas.

Number Guessing Program using java: The player has to guess a number given in between a range. If the guessed number is right, the player wins else, loses. It also has the concept of limited attempts where the player has to guess the number within the limited attempts given. Note: It must incorporates the following OOP components: - Classes - Objects - Constructors - Class Variable - Object Method
Information: Java Script There are two types of accounts - S for short term contract and L for long term contract. 3.1 Create an Employee objects project. Create an Employee class and use the provided UML diagram to code the instance fields, constructors and methods. 3.1.1 Both constructors must increment the static numberOfEmp field by one. Both constructors must call the setEmpCode() method to compile a code for the employee. Both constructors must call the setCommission() method. 3.1.2 setEmpCode() method: The empCode must be constructed in the following way: First character is the type of contract Next three characters a random 3 digits Add a backslash and the number of objects value to the code NOTE: You have to use the Random class in your code (See Ch 9). Do NOT use the Math.random() method. Example of code: S781/1 Explanation: Short term contracts (S), 781 is the 3-digit random value, first employee object. 3.1.3 setCommission() method: Assign a basic amount to the…
