Solve B please(A) Write a class called Course having data members: courseNum (String such as ITCS214), courseName (String such as Data Structures), credits (int), section (int). Include the following public methods in the class: Default constructor (without any parameters), constructor with 4 parameters, set and get methods for all attributes, equals and toString methods (B) Write a class called Student having following data fields: idNum (long), firstName (String), lastName (String), gender (char), email (String), coursesRegistered (ArrayList of type Course). Note that coursesRegistered is a list of type ArrayList (Java class) in which each element is of class type Course. The coursesRegistered is the list of courses in which the student is currently registered. It has following methods: Default constructor (without any parameters), constructor with 5 parameters (except for coursesRegistered), set and get methods for all attributes, equals, and printCoursesRegistered. The list…
Q# Which of the following might have only method signatures? Group of answer choices 1. An interface 2. An abstract class and a concrete class 3. An abstract class 4. An interface and an abstract class 5. None of these, they all require the implementation. 6. A concrete class
Match the following: A class that contains no methods (other than constructors) that change any of the data in its object modifier means that there are no restrictions on where an instance variable or method can be used hiding implementation details is done by marking data and methods as When we call a method in Java using class type parameters Overloading is achieved when two or more methods in the same class have the same…
1.How do we gain access to private attributes outside of the class they are defined? Through public methods Through static methods Through private methods Through the class identifier 2. If you were designing a class called Point and the class had a static variable or function, which of the following would either define or use it correctly? self.x = x self.increaseNumPoints() def mystery(self, x, y): Point.numPoints += 1 3.To promote security and object ecapsulations, object attributes should be declared as: static protected private public 4. Two underscores ( __ ) will precede: public attributes private attributes public methods private methods Both public attributes and methods both private attributes and methods 5. Which of the following is required in a class to create unique…
Which of the following statements are true. a) An abstract method contains a signature but no code implementation. b) We cannot create an instance of an abstract class by using the new operator. c) We can derive classes from an abstract class, but we must provide code to implement all of the abstract methods. d) All of the above statements are true.
Which (if any) of the following conditions are necessary for using polymorphism? Select all correct answers. The classes involved are in the same hierarchy. None of the classes can be abstract. All of the subclasses involved override the same method. The object reference cannot be of an interface type. An object reference of the superclass is used to call any methods. A superclass object is referenced by a subclass reference. Which of the following (if any) are true of abstract methods? Select all correct answers. Abstract methods must have a method body. Abstract methods cannot be declared in a class that isn't abstract itself. Abstract methods cannot be private or static. Abstract methods can only be declared in an interface. Abstract methods cannot be called. Constructor methods can be abstract.

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;
This is the question - Create an abstract NewspaperSubscription class with fields for the subscriber name, address, and rate. Include get and set methods for the name field and get methods for the address and subscription rate; the setAddress() method is abstract. Create two subclasses named PhysicalNewspaperSubscription and OnlineNewspaperSubscription. The parameter for the setAddress() method of the PhysicalNewspaperSubscription class must contain at least one digit; otherwise, an error message is displayed and the subscription rate is set to 0. If the address is valid, the subscription rate is assigned $15. The parameter for the setAddress() method of the OnlineNewspaperSubscription class must contain an at sign (@) or an error message is displayed. If the address is valid, the subscription rate is assigned $9. Code I was given - public class DemoSubscriptions { public static void main(String args[]) { PhysicalNewspaperSubscription pnsGood = new…
Given the following Imagine that is attached, select that all apply A. If the Other class extends the Base class then the method guessNumber() in Other overloads the method guessNumber in Base B. If the Other class extends the Base class then the method guessNumber() in Other overrides the method guessNumber in Base C. If the Base class implements MyInterface then it must implement the guessName method or declare it abstract. D. If the Base class implements MyInterface, then every class that extends the Base class also implements MyInterface. E. If the Other class extends the Base class, and implements MyInterface then the Base class also implements MyInterface F. MyInterface can have private methods specified.
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…
