Given this class, please add the requested methods in the designated spaces provided. Instance methods: a) Write two constructors that will initialize the instance variables for a Student instance as follows: 1) Write a constructor that takes in three parameters – an int, a String, and a double. The constructor will assign them to the ID, name, and GPA instance variables respectively. 2) Write a no-argument (zero-parameter) constructor that will set the ID to - 1, the name to “No name assigned”, and the GPA to –1.0. b) Write an accessor method for the name variable. c) Write a mutator method for the GPA variable. d) Write a toString() method that will display all three instance variables on a single line, with a | (vertical bar) character between each one. e) Write an equals() method that returns true only if all three instance variables are equal. public class Student { // declare instance variables here private int ID; private String name; private double GPA;

Select all the members of the class that are accessible by an instance method in the given class below. Note: Exclude the constructor(s) in your answer.
1) Change the visibility of the variables and constructor in the Employee class to be more secure 2) Add an Admin class with the following features: a) The Admin class is a child of the Employee class b) Admin objects have an instance string password variable c) The Admin class has a 4 parameter constructor. One parameter sets the string, the other three parameters are used as arguments for a parent constructor call. d) Admin objects have an instance getInformation() method with a void return and an Employee object parameter. The method will request the calling Admin’s password and check user input. If input matches the password, the method will display the information of the Employee parameter Please use ***C Sharp** Language to answer the code
Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name (a string) to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's 10.0 34.0 2.0 1.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is: Nutritional information per serving of None: Fat: 0.00 g…
tri1 and tri2 are instances of the Triangle class. Attributes height and base of both tri1 and tri2 are read from input. In the Triangle class, define instance method print_info() with self as the parameter to output the following in one line: 'Height: ' The value of attribute height ', base: ' The value of attribute base
What does the super keyword represents and where can it be used? Give an example of a superclass and subclass. Be sure to make all the instances variables of the super class private. Include at least one constructor in each class and ensure that the constructor of the subclass calls the constructor of the superclass. Also include a toString method in both classes that returns the values of the instance variables with appropriate labels. Ensure that the toString method of subclass calls the toString method of the superclass so that the string returned contains the values of all the inherited instance variables.
(1) Add an __init__ method to the Widget class below. Each object of type Widget should have an instance variable called name and an instance variable called cost that represents a cost in dollars; those values are passed in when an object of type Widget is initialized. (2) Add a method to class Widget called is_cheap that returns True if the cost is less than $10, and False otherwise. (3) Add proper doctrings along with two examples for each method. You may use the Sample Usage code given below in your work.
For this portion of the assignment you will need to create the Employee class * based on the instructions in the API and have implemented the Equals method for that class. * * There is one parameter being passed as to this method that you will use as part of your solution:* An Employee object reference with the identifier testEmployee* * 1) Instantiate an instance of the Employee class using the default constructor and * assign it to an object reference with the identifier defaultEmployee* * 2) Instantiate an instance of the Employee class using the alternate constructor, * passing the following arguments:* name: "Keanu Reeves"* ID: 10010* salary: 78000.00* Assign the instance to an object reference with the identifier keanuEmployee* * 3) Declare a variable of type Employee with the identifier excellentEmployee and assign it * a reference to the same object that is being referenced by the keanuEmployee object reference. * 4) Construct a selection statement that tests if testEmployee is…
Modify the student class presented in this chapter as follows. Each student object should also contain the scores for three tests. Provide a constructor that sets all instance values based on parameter values. Overload the constructor such that each test score is assumed to be initially zero. Provide a method called setTestScore that accepts two parameters: the test number (1 through 3) and the score. Also provide a method called getTestScore that accepts the test number and returns the appropriate score Provide a method called average that computes and returns the average test score for this student. Modify the toString method such that the test scores and average are included in the description of the student. Modify the driver class main method to exercise the new Student methods. (c++ language)

Create an abstract class called vehicle. The class should declare the following variables: an instance variable that describes the model - String an instance variable that describes the number - String an instance variable that describes the maker - String an instance variable that describes the price - double an instance variable that describes the year – integer Provide a toString() method that returns the information stored in the above variables. Create the getter and setter methods for each instance variable except price. Provide the necessary constructors. Include an abstract method setPrice(double price) to determine the price for a vehicle. Include an abstract method getColor() to return the color of the vehicle. Create two subclasses called Car and Truck . These subclasses should override the abstract methods setPrice and getColor of class vehicle. Use the following rule for setting the price for a vehicle: car will have a 30% discount per each vehicle truck…
In the following there are two classes, Employee and Manager. Manager is a subclass of Employee. The implementation of Employee class is given (Note: no getter methods are provided, so you are not able to access instance variables through getter methods in the subclass). The skeleton of the Manager class definition is given. Complete the constructor method, and the toString method for the subclass (see the details below). public class Employee { private String name; private double salary; // Make an employee with a given name and salary. public Employee(String aName, double aSalary) { name = aName; salary = aSalary; } // Provide a string description of an employee. public String toString() { return "Name: " + name + "\tSalary: " + salary; } } public class Manager extends Employee { private String department; // Make a manager with a given name, salary, and department. public Manager(String name, double salary, String department) { // put your code below } // Provide a string…
