- 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.Create a class Reverse with one data member called num of type int and a static method find to return reverse of num. Create a subclass ReverseR from Reverse which overrides member of its super class. Write a main() method that tests in same class ReverseR. method find()) and this override method uses recursion to find and returns reverse of dataWrite a Java class Student inherited from Person class. Your class must have the following features: Student - major: String + Student() + Student(name: String, id: int, major: String) + getMajor(): String + Override toString() method: you have to return needed data Fields values. Note: major data members can take only CS for Computer Science, CIS for Computer and Information Systems, CPE for Computer Engineering, SE for Software Engineering, and NES for Network Engineering and Security.
- The class diagram below shows an Order class that "has a" Customer and zero or more Items. Order class should contain private Customer m_cust; private ArrayList<Item> m_items; public Order(Customer cus t) public void additem(Item i) public String toString() Item class should contain private String m_desc private int m_qty private double m_price public Item(String des c, double price, int qty) public String toString() Customer class should contain private String m_first; private String m_last; public Customer(String first, String last) public String toString() Please create the Order, Customer, and Item classes shown above. I have provided you with a read-only Main class that you can use to test your code. When you have completed the Order, Customer, and Item classes, running the Main program should produce the following output: Order for Smith, Tom Order Items: Greeting Card: 1 at 1.5 Baseball Glove: 1 at 54.0 Notebook: 3 at 2.5 public class Main{ public static void…In Java, Write a line of code that performs each of the following tasks : (a) Call superclass Employee's toString method from subclass Pieceworker's toString method.

- Java- Suppose you write a new constructor for an extended class. Describe two different ways that the superclass's instance variables could be initialized within the constructor for the extended class.In Java The base class Pet has protected fields petName, and petAge. The derived class Cat extends the Pet class and includes a private field for catBreed. Complete main() to: create a generic pet and print information using printInfo(). create a Cat pet, use printInfo() to print information, and add a statement to print the cat's breed using the getBreed() method.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.
- Write a java program in which Animal:Create a class Animal and Add a protected data member named id of integer type.• Add get/set methods for id data member in Animal class with public access. Also provide default constructor this should initialize id to 0.• Also provide parameterized constructor and toString method.• Add an abstract method tellAboutSelf method to Animal class with public access• Add another abstract method speak method to Animal class.Reptile, Bird, MammalNext create the three child classes which extends form Animal class.• Add a default constructor to each of the above created class. The constructor should initialize the id data member id, Reptile, Bird and Mammal, to 1, 2 and 3 respectively also it display a message “(class Name)’s default constructor”. E.g. for Bird it says “Bird’s default constructor”.• Add a parameterized constructor to each of the above created class. The constructor should initialize the id data member, Reptile, Bird and Mammal, to the…Write a Java class Person for dealing with persons. Your class must have the following features: Person id: long name: String gender: String + Person() + Person (id: long, name: String, gender: String) + Create setter and getter for all data fields. + Override toString() method: you have to return required data Fields values. Constructor: public Person(): A default constructor, should initialize the data fields to their default values. public Person (SSN: long, name: String, gender: String): A constructor with parameters, that creates the person object by setting specified parameters. Instance methods: public void setName(name: String): Used to set the full name of the person. public void setGender(gender: String): Used to set the gender of the person. public long getId(): This method returns the id of the person. public String getGender(): This method returns the gender of the person. public String getName(): This method returns the full name of the person. public String…Consider the following class definitions public class SampleClass{ public String greet() {return "Greetings";} } public class SubClass extends SampleClass{ public string greet() {return "Hello";} } public class AnotherClass{ public String greet() {return "Hi";} } What can be said about the following code fragment? public class Driver { public static void main(String[] args){ Object p =new SampleClass(); System.out.println((AnotherClass).p),greet()); } } a. The above code compiles but causes runtime error. b. The above code has no issues. It compiles and runs. c. The above code causes compiler error.
