- In Java programming (Lesson: Objects, Classes, and Constructors) Every class has a constructor and if we do not explicitly write a constructor for a class, the java compiler builds a default constructor for that class. False or True Please provide an explanation for the answer. Thank you!I'm learning java in college and I missed one homework assignment. Since then it has been difficult to keep up with homework because they were based on the one I missed. Here's the prompt: Design a class Phone with one data member as long phoneNumber. Add constructors, get/set methods to class Phone. Then design a class InternationalPhone as subclass of class Phone, with one extra data member as int countryCode. Add constructors, get/set methods to class InternationalPhone. Write a main program to test these two classes. (We use netbeans btw) I can't get any credit for this so there's no rush but I would be very happy to recieve an answer before the end of the semester. Thank you in advance :)Please follow the steps to complete JAVA PROGRAM Create a class, EmployeeException, that has the following attributes: name: String SSN: String Salary: double The methods required in this class are: A constructor with no arguments that sets the attributes at default values A constructor that passes values for all attributes Accessor, mutator, display method for each attribute. An example of a display method for an attribute is writeOutName(): void, in which you just display the name:System.out.println("Employee Name: " + name); An equals method that has an object of type Employee as argument, and returns true if two employees have the same name, salary, and SSN. Write a driver program for the Employee class that uses an array that can hold up to 100 employees (the array will be of EmployeeException type). However, the user should be free to enter as many employees as needed. The driver class should use two exception classes to signal the user that the SSN entered is not correct.…
- For beginning Java: The Person, Student, Employee, Faculty, and Staff classes 1) Design a class named Person and its two subclasses named Student and Employee. Make Faculty and Staff subclasses of Employee. A person has a name, address, phone number, and e-mail address. A student has a class status (freshman, sophomore, junior, or senior). An employee salary (double), and date hired. Use the java.time.LocalDate class to create an object for date hired. A faculty member has office hours (example: “Friday 3-4PM”) and discipline (like “Computer Science” or “Math”). A staff member has a title. Override the toString method in each class to display the class name and all related data. Draw the UML diagram using MS Word or PowerPoint for the classes and implement them. 2) Write a test program that creates a Person, Student, Employee, Faculty, and Staff, and invokes their toString() methods. Your program needs to read a text file containing data for these objects. One line for each object.…Write a program in Java that performs the following tasks: Creates a class called Person having attributes personName, personID. Creates a subclass called Student of Person class having attributes stdGPA, stdMajor. Creates a subclass called Teacher of Person class having attributes teacherCourse, teacherSalary. Write the constructors for Person, Student and Teacher class to initialize the attributes(fields). Write a method displayDetails() in Student and Teacher class to print all attributes of superclass and subclass.in Java Part 1 : Start by creating a new class called MyPoint that can be initialized with either of these constructors: MyPoint p1 = new MyPoint(); MyPoint p2 = new MyPoint(2.0, 4.0); The two arguments given to the constructor are x (2.0) and y (4.0) co-ordinates. Don’t forget to include getters and setters as these should be private instance variables! Part 2 : Create a toString() instance method that prints out the co-ordinates of the point. Add two instance methods that return the Euclidean distance to another point, or to another (x, y) coordinate. Example: double distance = p2.distance(p1); The Euclidean distance between two points is: d=√x^2 + y^2 You will need to make use of methods from the Math package: https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/lang/Math.html Test your constructors and the new methods. Part 3 : Create a class method, contains(MyPoint[] points, MyPoint p), that checks if the point p is in the array points and returns a boolean.…

You will need to create a class that implements the iAnimal interface (provided below), and use one other class for an additional animal that implements the iAnimal interface as well (provided below). Modify the animal classes that you will use for this project so they implement Java’s comparable or comparator interface. You will also need a Main Class that will provide a user interface for this application. This can be a console-based interface. Tasks can be performed in one or more methods as needed. The Main Class should have one or more methods that handle these tasks: Create a new instance (object) of each of the animal classes and pass the user input as arguments to the object's mutator methods to set the private instance data for the appropriate animal class. Create an ArrayList of type iAnimal and add the new instance created in task 1 to the ArrayList. Before…Write a complete Java class that can be used to create a Fish object as described below: A Fish has-a: - name age - type favorite food a) Add all instance variables b) The class must have getters and setters for all instance variables c) The class must have two constructors: a no-args constructor and a constructor that receives all data fields as parameters d) The class must have a toString() e) Add a main method and create 2 Fishes using each of the constructors you created
