Given a Student class, and UndergradCourse is a true subtype of Course, there is one method called recommend in the Student class: public class Student { public Course recommend(Course pCourseID); } Please evaluate if EACH of the method in UndergradStudent class violates the Liskov Substitution Principle. public class UndergradStudent extends Student { 1. public Course recommend(UndergradCourse pCourseID); 2. public UndergradCourse recommend(Course pCourseID); 3. public UndergradCourse recommend(Object pCourseID); 4. public Course recommend(Course pCourseID) throw SomeCheckedException;

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.
Sally and Harry implement two different compareTo methods for a classthey are working on together. Sally’s compareTo method returns −1, 0, or +1,depending on the relationship between two objects. Harry’s compareTo methodreturns −6, 0, or +3. Which method is suitable?
Can you implement the Derived Class Parameterized constructor? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. Implement the constructor Dell(String name) of the Derived Class Dell which takes a string, name. We have already implemented the Base Class Laptop with the member function getName() and a parameterized constructor. Input# Laptop name is being passed through the parameterized constructor. Output# getName() method is returing Laptop name. Sample Input# Dell dell = new Dell("Dell Inspiron"); Sample Output# "Dell Inspiron"
Java program Make a class Employee with a name and salary. Make a class Manager inherit from Employee. Add an instance variable, named department, of type String. Supply a method toString that prints the manager’s name, department, and salary. Make a class Executive inherit from Manager. Supply appropriate toString methods for all classes. Supply a test program that tests these classes and methods.
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
There is a class called Roster whose constructor that takes a List of tuples with the names of students and their grades in the class. for example -- [("Richard",98), ("Benny",55),("Katie",87),("Sally",76)]. Create an instance of the Roster class, including the following students and their respective grades, and store it in the variable mathClass: Jacob,65 Frankie,86 Lina,94 Arnold,63 Amanda,87 using python
All vehicles used for transportation in the U.S. must have identification, which varies according to the type of vehicle. For example, all automobiles have a unique Vehicle Identification Number (VIN) assigned by the manufacturer, plus a license plate number assigend by the state in which the auto is registerd. Modify the Auto class to include an instance variable for the license plate number. Implement the constructor so that an Auto can be constructed with a VIN and a license plate number. Override the getID() method to return the id of the auto as shown in this format: VIN=1234567890,plate=ABC123 (without any spaces). ** Represents an automobile.*/public class Auto // TODO: Inherit from Vehicle{ // TODO: Declare instance variables public Auto(String vin, String plate) { // TODO: Complete the constructor } // TODO: implement the getID() method for autos}
We have two classes, Person and Employee. Both have a field, firstName. We have instances of these objectsPerson p and Employee e. Both p and e have the same value for firstName, specifically, p.firstName = “joe”and e.firstName = “joe” Which of the following statements is necessarily true? Group of answer choices 1. p.equals(e) will return true because they contain the same firstName. 2. We don’t know if either class will have an equals method. 3. There is not enough information to tell what p.equals(e) will return. 4. p.equals(e) will return false but p == e will be true.
All vehicles used for transportation in the U.S. must have identification, which varies according to the type of vehicle. For example, all automobiles have a unique Vehicle Identification Number (VIN) assigned by the manufacturer, plus a license plate number assigend by the state in which the auto is registerd. Your task is to modify the Auto class below to override the equals method of the Vehicle class to test that the VIN and license plate number are identical.
