- 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.//Todo write test cases for SimpleCalculator Class // No need to implement the actual Calculator class just write Test cases as per TDD. // you need to just write test cases no mocking // test should cover all methods from calculator and all scenarios, so a minimum of 5 test // 1 for add, 1 for subtract, 1 for multiply, 2 for divide (1 for normal division, 1 for division by 0) // make sure all these test cases fail public class CalculatorTest { //Declare variable here private Calculator calculator; //Add before each here //write test cases here }1) Through BlueJ, the class must define a method called isSpace that allows the book club staff to determine whether there is enough capacity for a group to attend. This method must take a single integer parameter representing the size of the group, and return a boolean result. The method must work as follows: If the value of the parameter is less-than or equal-to 0 then the method must return false. This case has priority over those following. If the value of the parameter is less-than or equal-to the space left in the book club (use the capacity and occupancy values in the to work this out) then the method must return true. Otherwise (i.e., if there is not space in the book club for the whole group) then the method must return false. 2) This method must not change the state of the BookClub object. In other words, both the current number of occupants and the capacity of the club must be exactly the same after it is called as it was before (Note that the return type of this method…
- USING C++ Random Number Guesser Write a derived class of the NumberGuesser class named RandomNumberGuesser. The derived class should override the behavior of the getCurrentGuess method. It may also add member data and its own constructor. It may also override the higher(), lower() and reset() methods as you see fit. I have written a NumberGuesser class to make things easier. // NumberGuesser.h #ifndef NUMBERGUESSER_H #define NUMBERGUESSER_H #include <iostream> class NumberGuesser { protected: int low; int originalLow; int high; int originalHigh; public: NumberGuesser(int l, int h) { low = originalLow = l; high = originalHigh = h; } virtual int getCurrentGuess() { return (high + low) / 2; } virtual void higher() { low = getCurrentGuess() + 1; } virtual void lower() { high = getCurrentGuess() - 1; } virtual void reset() { low = originalLow; high = originalHigh;…•Person Class: Person class has attributes: String name, address and int age.

A Worker has a Worker Name and Number. Write the class XXXX_ProductionWorker which is a subclass of Worker. The production worker has a shift number (values: 1 or 2) and an Hourly pay rate. A shift number of 1 means the day shift and 2 means the night shift. Write the class XXXX_ShiftSupervisor which is a subclass of Worker. The shift supervisor is a salaried worker who supervises a shift. The shift supervisor has a yearly bonus field. The yearly bonus is earned at year end based on performance. Write a class, XXXX_TestWorker, which does the following: Creates one Shift Supervisor object from information entered by the user. Creates an Array of Production Workers that can hold 3 objects. Itcreates3ProductionWorkerobjectsfrominformationenteredbytheuser Prints the information about each object in the format shown below using the toString methods of the…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
- Implement the Seller class as a derived class of Person class. Create the seller.h and seller.cppfiles for this class. The Seller class contains additional data members that hold a seller’s:o average star rating received from the buyers, ando total number of items sold.These data should be accessible by its derived classes. (should these data be private, public, orprotected?) The following methods are included in the seller class:• A default constructor and a copy constructor• A constructor that receives all of the data for a seller.(for the constructors, make sure to call the base class constructor as appropriate)• Appropriate get and set functions for the new data in this class• print() – overrides the base class print() to print the base class data and print all additionalseller data with appropriate messages. Make sure to call the base class print to print thebase class data.• read() – overrides the base class read() to read the base class data and reads all additionalseller data…constructor that sets all instance variable to a given values. instanc variables: Full name( service(int), monthly salary (double) Method to print information of the employee. B: Create a class called Employee that includes five pieces of information as: yearly salary for them.Software Requirements: • Latest version of NetBeans IDE • Java Development Kit (JDK) 8 Procedure: 1. our progras from rhFactor non-static and private. Remove the constructor with two (2) parameters. 2o upply uncapsutation Make bloodType and 2. The names of the public setter and getter methods should be: • setBloodType() • setRhFactor() getBlood Type() getRhFactor() 3. Use the setter methods to accept user input. 4. Display the values by calling the getter methods. Sample Output: Enter blood type of patient: Enter the Rhesus factor (+ or -): O+ is added to the blood bank. Enter blood type of patient: B Enter the Rhesus factor (+ or -): B- is added to the blood bank.
