Why do we use generic methods? Generic methods allows for code reuse (for different data types) Generic methods allows for the Object class (the generic data type) to be used Generic methods allow for handling abstract class (of which there can be no instantiations) The compiler will automatically generate test cases based on the appropriate data types

Write a C# program that uses a class called ClassRegistration as outlined below: The ClassRegistration class is responsible for keeping track of the student id numbers for students that register for a particular class. Each class has a maximum number of students that it can accommodate. Responsibilities of the ClassRegistration class: It is responsible for storing the student id numbers for a particular class (in an array of integers) It is responsible for adding new student id numbers to this list (returns boolean) It is responsible for checking if a student id is in the list (returns a boolean) It is responsible for getting a list of all students in the class (returns a string). It is responsible for returning the number of students registered for the class (returns an integer) It is responsible for returning the maximum number of students the class is allowed (returns an integer) It is responsible for returning the name of the class. (returns a string)

Design an interface Polynomial that defines the following operations. This is your polynomial abstract data type. Specifically this interface should have the following method signatures: A method addTerm that takes a coefficient and a power (both integer numbers) and adds the resulting term to the polynomial. (This will enable you to build a polynomial term-by-term.) It should throw an IllegalArgumentException if a negative power is passed to it. A method removeTerm that takes a power and removes any and all terms in the polynomial with that power. A method getDegree that returns the degree of this polynomial. A method getCoefficient that takes a power and returns the coefficient for the term with that power. A method evaluate that takes a double-precision decimal number and returns a double-precision result. A method add that takes another Polynomial object and returns the polynomial obtained by adding the two polynomials. Any implementation should ensure that this method does not…
Inheritance, Polymorphism, ArrayLists, Throwing Exceptions The UML diagram below shows a set of classes designed to represent a music collection from 1995. The constructors and methods all function in the standard way, except: The equipmentRequired method should return “Record Player” or “CD Player” as appropriate.The getAlbum method of the NinetiesMusicCollection class accepts an index and returns the corresponding Album object. This method throws an IllegalArgumentException if the index is out of range. (This is the only exception you have to throw anywhere in your code.)In the NinetiesMusicCollection constructor, you can assume the ArrayList<Album> object passed as an argument is not null . Don’t worry about privacy leaks.Implement this set of classes in Java. Note the italics on the Class name “Album” and the method name “equipmentRequired” in the Album class.
Implement a nested class composition relationship between any two class types from the following list: Advisor Вook Classroom Department Friend Grade School Student Teacher Tutor Write all necessary code for both classes to demonstrate a nested composition relationship including the following: a. one encapsulated data member for each class b. inline default constructor using constructor delegation for each class c. inline one-parameter constructor for each class d. inline accessors for all data members e. inline mutators for all data members
When a concrete class inherits from an abstract class, you have to implement all abstract methods declared in the super class before you can instantiate it (the concrete class). True False
Classes: Write a Person class that has these attributes: person_ID, first and last names, and age Default and overloaded constructors Accessors and mutators equals method toString method (make this virtual if C++, don't forget to prep the class for polymorphism) Inheritance: Create a child class to Person called Student: Attributes: GPA and status (freshman, sophomore, junior, senior, graduate, graduated). Make sure you have appropriate accessor/mutator methods Create another child class to represent Faculty. This class will have faculty rank and length of service as attributes along with an office location. Again, add methods as needed. Application Create an application that displays a menu that allows users to add students or faculty, or print either one or exit. Deliverable: Submit your source code and classes on Github (you will be supplied an account) You will also submit a Word document and your code on Canvas. In the document you iwll write a summary of your design…
T or F -Functions are considered to be objects in JavaScript because they contain three critical attributes: data, methods that act on the data, parameters for passing the data also known as awareness. -A recursive function is a function that calls itself and eventually returns default value to break out of the recursion. -A function that is used to create a new object is called an anonymous function. -Attributes define additional characteristics or properties of the element which is the same as for the start tag. -Javascript is similar to the Java programming language
