- Java programming Help us set up the student system! 2.a) Write an abstract class Student describing (students) (2 properties and 1 method)! (Be carefull when defining the method!) 2.b) Extend the Student class into three new classes that can be directly instantiated: UndergraduateStudend, PostgraduateStudent, FailedStudent (each should have one additional property)! 2.c) Use all appropriate classes in a special School class!Convert the UML class diagram above into a java code with the following conditions The methods in the Pet class are abstract. Create a class called test. The main() method in the test class should create three Cat objects and two Budgie The main() method should also create indirectly an object of the Pet class. Demonstrate polymorphism in your testQuestion 2: Recall and apply the concepts of object oriented programming (Java) (iii) We have to calculate the percentage of marks obtained in three subjects (each out of 100) by student A and in four subjects (each out of 100) by student B. Create an abstract class 'Marks' with an abstract method 'getPercentage'. It is inherited by two other classes 'A' and 'B' each having a method with the same name which returns the percentage of the students. The constructor of student A takes the marks in three subjects as its parameters and the marks in four subjects as its parameters for student B. Create an object for eac of the two classes and print the percentage of marks for both the students.
- language: Java Class Inheritance with an abstract class Define a class Employee with the following fields: _name, _empId, _department, _position (_title), _yearlySalary, _fullTime (a boolean: true/false) , _month , _year (time of hire) Add constructor and properties Define an abstract method GetBiMonthlySalary() (if the employee is paid twice a month) Define an abstract method GetVacationTime() that returns the number of vacation time this employee would have based on time of hire Override the ToString() method to return a string that contains the information pertaining to an employee such as name, empId, department, and where full time or not. Define a class HourlyEmployee that inherits from Employee. This class should have 2 fields of its own: _hours (hours worked in half a month) and _wage (hourly wage) Provide necessary constructor, properties and methods Override the ToString() to also return the additional fields Gets 3 days of vacation after first year if the…Subject: Java Programming Question#1: Define an abstract class LivingBeing. Define abstract methods breath, sleep, eats. Define Subclasses Animal and Plants. Override the base methods and call them polymorphically.Weite java code to implement given statements An abstract class must be declared with an abstract keyword.• It can have abstract and non-abstract methods.• It cannot be instantiated.• It can have constructors and static methods also.• It can have final methods which will force the subclass not to change the body of the method.
- JAVA PLEASE Create an inheritance hierarchy for farm animals with the abstract parent class animal, at least three child classes, and 1 interface. Note, you should include an abstract method in animal that is defined in the child classes, and one abstract method in the interface that is implemented. (This is not a program, it should resemble UML as best as it can).Class A is the top-level category, while classes B and C are its children. So, although B and C have certain common characteristics and methods, B and C's implementations of a number of those methods are quite different. Use reasoning to determine if A will be a concrete class, abstract class, or interface.246. The process of forming a new class from an existing class. a. Abstraction b. Polymorphism c. Inheritance d. Implementation
- This is an object oriented programming question. The code should be in C++ language Consider an abstract class Computer having Two fields (i.e. companyName, price) and A single function named show() A class named Desktop inherits Computer class and adds fields representing color, monitor size, and processor type and A parameterized constructor to initialize its own data members as well as the inherited data members Override function named show() to display values of its all attributes A class named Laptop inherits Computer class and adds fields representing color, size, weight, and processor type and A parameterized constructor to initialize its own data members as well as the inherited data members Override function named show() to display values of its all attributes Write a main() function that instantiates objects of derived classes to call respective show() function using dynamic or late binding.Write a c++ program to implement the hierarchical inheritance 1. Write getter/setters, display function, parameterized, default and copy constructor. 2. Write a calculateSalary() function in the Typist class and override the definition in permanent and casual. 3. Write a ‘main’ function and create objects of all classes in main and call the public methods of all classes.1.Write java classes to hold Account, SB-Account and Current-Account details. [Here implement the concept of inheritance.] The common properties of the account are Account number, name and amount. Specifics of SB account is 4% interest to be paid per month. Implement the run time polymorphism by creating base class variable and derived class object. Ask the user for which type of account to be created then create the corresponding account (Note: Use scanner class). Implement function overriding by having deposit and withdraw functions and perform the required action accordingly. Ensure base class can’t be instantiated. (Note: Abstract keyword can be used). 2.Define the minimum balance for the both the type of accounts. Use final keyword to create constants. Ensure sb account class and current account class will cannot be used as base classes (Note: You can use final classes).
