a) write the definition of the 4 methods as described in the definition of the clas TestClass.b) write a complete demo test program with the main() to test All of the operations of the TestDemoClass class. Sure! Here's the transcription as if it will appear on an educational website:---**Understanding Class Definitions in Java**In this example, we are given the definition of a simple Java class named `TestClass`. This class demonstrates basic class structure in Java, including private variables, constructors, and methods.```javapublic class TestClass{ private int x; private int y; // Default constructor to initialize the instance variables to 0 public TestClass() { // Implementation details } // Constructor with parameters to initialize the instance variables // to the values specified by the parameters public TestClass(int a, int b) { // Implementation details } // Return the sum of the instance variables public int sum() { // Implementation details } // Print the values of the instance variables public void print() { // Implementation details }}```**Key Components:**- **Instance Variables:** The class has two private instance variables, `x` and `y`, of type `int`.- **Constructors:** - The default constructor initializes the instance variables `x` and `y` to zero. - An overloaded constructor accepts two parameters, `a` and `b`, to initialize the instance variables.- **Methods:** - `sum()`: This method returns the sum of the instance variables `x` and `y`. - `print()`: This method outputs the values of `x` and `y`.This example provides a foundational understanding of how to structure a class in Java, manage instance variables, and implement basic functionality through methods.

I also am struggling with this project but do not understand this code. The problem I have uses a main.cpp file alongside a dateTypelmp.cpp file. This solution does not solve the task as I understand it to be. The class dateType was designed to implement the date in a program, but the member function setDate and the constructor do not check whether the date is valid before storing the date in the member variables. Function setDate and the constructor need to be rewrit so that the values for the month, day, and year are checked before storing the date into the member variables. A member function should be included, isLeapYear, to check whether a year is a leap year. Input should be format month day year with each separated by a space. Output should resemble the following: Date #: month-day-year If the year is a leap year, print the date and a message indicating it is a leap year, otherwise print a message indicating that it is not a leap year. The header file for the class dateType has…
please may you : create a Python class named Animal with properties for name, age, and a method called speak. also include an initializer method for the class and demonstrate how to create an instance of this class. and extend the Animal class by adding a decorator for one of its properties (e.g., age). please include both a getter and a setter for the property, and demonstrate error handling.

Complete the Course class by implementing the courseSize() method, which returns the total number of students in the course. Given classes: Class LabProgram contains the main method for testing the program. Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. Ex. For the following students: Henry Bendel 3.6 Johnny Min 2.9 the output is: Course size: 2 public class LabProgram { public static void main (String [] args) { Course course = new Course(); // Example students for testing course.addStudent(new Student("Henry", "Bendel", 3.6)); course.addStudent(new Student("Johnny", "Min", 2.9)); System.out.println("Course size: " + course.courseSize()); } } public class Student { private String first; // first name private String last; // last name private…
Write a method for the farmer class that allows a farmer object to pet all cows on the farm. Do not use arrays.
B elow for each class you find a UML and description of the public interface. Implementing the public interface as described is madatory. There's freedom on how to implement these classes.The private properties and private methods are under your control.. There are multiple ways of implementing all these classes. Feel free to add private properties and methods. For each object, it's mandatory to create a header file (.h), implementation file (.cpp) and a driver. Blank files are included. The header should have the class definition in it. The implementation file should contain the implementations of the methods laid out in the header fine. And finally the Driver should test/demonstrate all the features of the class. It's best to develop the driver as the class is being written. Check each section to see if there are added additional requirements for the driver. Two test suites are included so that work can be checked. It's important to implement the drivers to test and demonstrate…
I've gotten stuck on this practice problem. I need help figuring this out. You need to make a Pet class that holds the following information as private data members: the name of the pet (e.g. "Spot", "Fluffy", or any word a user enters) the type of pet (e.g. dog, cat, snake, hamster, or any word a user enters) level of hungriness of the pet (2 means hungry, 1 means content, 0 means full) Your class also needs to have the following functions: a default constructor that sets the pet to be a dog named Buddy, with level of hungriness being “content” a parameterized constructor to allow having any type of pet the order of the parameters is: name of the pet, type of pet, hungriness level a PrintInfo function that prints the info for the pet according to the sample output below a TimePasses function that increases the hungry level of the pet by one (unless its hungry level is already 2, meaning hungry). a FeedPet function that changes the hungry level of the pet to 0 (Full) You must…
is this just for the candidate class or is the election class included?
82. Write a class definition for a class named Fraction that contains two integer fields named numerator and denominator. Include in the class a prototype for a method (function) named add that takes two Fraction objects as input arguments and returns a Fraction object as output. You do not need to provide an implementation of the add method.
