- Java program Make a class Employee with a name and salary. Make a class Manager inherit from Employee. Add an instance variable, named department, of type String. Supply a method toString that prints the manager’s name, department, and salary. Make a class Executive inherit from Manager. Supply appropriate toString methods for all classes. Supply a test program that tests these classes and methods.*using java* Create a class AnimalCreate a class Cat, and a class Dog, and a class Bearded Dragon which extend Animal. Add to your Animal class: Member: name Methods: Public Animal(String name) //constructor public void makesSound()with the implementation printing out a generic animal sound. Next, override (add) the makesSound()method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don’t make sounds!)Note, you’ll also need a constructor in each of your subclasses which calls super(name) to initialize the common ‘name’ member of Animal. --- Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each. ( you should observe the implementation of the makeSound() method called will be: cat -> from Cat class, dog-> from Dog class,…use java (ArrayList, inheritance, polymorphism, File I/O and basic Java) Student class: First, you need to design, code in Java, test and document a base class, Student. The Student class will have the following information, and all of these should be defined as Private: A first name (given name) A last name (family name/surname) Student number (ID) – an integer number (of type long) The Student class will have at least the following constructors and methods: (i) two constructors - one without any parameters (the default constructor), and one with parameters to give initial values to all the instance variables of Student. (ii) only necessary set and get methods for a valid class design. (iii) a reportGrade method, which you have nothing to report here, you can just print to the screen a message “There is no grade here.”. This method will be overridden in the respective child classes. (iv) an equals method which compares two student objects and returns true if they…
- Class Implementationa) Implement a class PlayCard with three attributes, rank, suit, and players.b) Implement an init method with an optional parameter type: 1) Set the default value of rank to "queen", suit to "hearts" and players to 4.c) Implement a display method to print the values of rank, suit, and players as the example output below.d) Instantiate two objects of type PlayCard, treasure with arguments "king", "diamonds", 2, and banker without any arguments.e) Call display() to print rank, suit, and players of treasure and banker.Just make sure to precisely match the output format below.Write your code in the ANSWER area provided below (must include comments if using code is not covered in the course)Example OutputRSP: king | diamonds | 2RSP: queen | hearts | 4Abstract in Java Employee Override the display method in the Person class override the toString() and equals() methods Define method earnings as abstract with a return type of double. Hourly Employee provide the setters and getters of your data members provide call to parent contructors earnings is computed by having the product of the total number of hours worked and the rate. but if the number of hours worked exceeds 40, the rate increases to 150% of the current rate. (ex. rate=200; 150% = 300) override the toString() and equals() methods Note:Class Person is already loaded in this activity. No need to add the class in your code.java Write a simple class to represent a Student. Each student object should have the following data items: A first natne, a lasl name, a student ID, and a GPA. Think carefully about how you should model this data and write getter (query) and setter (command) methods for each. Override public boolean equals(Object o) so that two student objects that have the same student ID are seen as equal
- Java- Suppose that Vehicle is a class and Car is a new class that extends Vehicle. Write a description of which kind of assignments are permitted between Car and Vehicle variables.Hand-write a complete Java class that can be usedto create a Car object as described below.a. A Vehicle has-a:i. Registration numberii. Owner nameiii. Priceiv. Year manufacturedb. Add all instance variablesc. The class must have getters and setters for all instance variablesd. The class must have two constructors, a no-args and a constructor that receivesinput parameters for each instance variable.FOR JAVA Part I Create a Company class that has at least three properties. Part II Write proper constructor and other methods required for the class (get & set, toString etc.) Part III Write at least 5 different methods considering the applications of Company class. Your methods must handle exceptions. Part IV Write a Test class and use the methods written in Company class.
- Please write a Java program with at least two classes. Use a circle to represent it! The class should have at least one non-static setter method and one non-static getter. Implement at least one method test that invokes the setter method and the corresponding getter method so that the value out == the value in!The Java Programming class has two types – remote and in-person. For remote students, the weighted score comprises of midterm, final, assignments and discussion. The weights for each are 30%, 30%, 30% and 10% respectively. For in-person students, the weighted score comprises of midterm, final and assignments. The weights for each are 30%, 30% and 40%. Write a generic class Students.java which has a constructor that takes three parameters – id, name, and type. Type will represent if the student is ‘remote’ or ‘in-person’. A toString() method in this class will display these details for any student. A generic method score() will be part of this class and it will be implemented by inherited classes. Write accessors and mutators for all data points. Write two classes RemoteStudents.java and InPersonStudents.java that inherits from Student class. Show the use of constructor from parent class (mind you, RemoteStudents have one additional parameter – discussion). Implement the abstract method…code to To achieve encapsulation in Java: Declare the variables of a class as private.Provide public setter and getter methods to modify and view the variables values.
