Add a tester where you make an array of 5 person and ask the user to enter them. Then loop over the array and print them. The user may enter a Student, a Staff or even a Person. The ‘-‘ symbol means private field or method and ‘+’ means public. The classes Student and Staff inherit from PersonModify the above code to use the alternative method for multithreading (i.e., implementing the Runnable interface). Name your main class RunnableHelloBye and your subsidiary classes Hello and Goodbye respectively. The fi rst should display the message ‘Hello!’ ten times (with a random delay of 0–2 s between consecutive displays), while the second should do the same with the message ‘Goodbye!’. Note that it will NOT be the main class that implements the Runnable interface, but each of the two subsidiary classes.
- Implement a class Season that represents a season during a specified year. For purposes of thisproblem, assume that the seasons in each year are, in order, 'Winter', 'Spring', 'Summer', 'Autumn' .__init__, __repr__A Season object is created by calling the constructor and supplying two optional arguments:1. season, defaults to 'Winter'2. calendar year, an int , defaults to 2023For the __repr__ , see the usage below: The next and prev methods modify a Season object by changing it to the next season or previousseason in sequence, respectively. Note that the seasons can "roll over" or "roll back" and that this maychange the year by +/-1. 1. During each year, the seasons occur in this sequence: 'Winter', 'Spring', 'Summer', 'Autumn' 2. next - change to next season, if the current season is Autumn then year will increase by 1 3. prev - change to previous season, if Winter then year will decrease by 1 Implement the == operator ( __eq__ method) to compare two Season…1) Consider the following class Date, which represents a date using three ints for month, day and year: class Date { private: int month; int day; int year; public: Date() { month = day = year = 0; } Date(int m, int d, int y) { month = m; day = d; year = y; } bool operator==(Date); bool operator<(Date); }; It asks to create an implementation for both overloaded operators. == should return true if the Date objects are equivalent and false if not. < should return true if the Date of the calling object (left object) comes before the parameter Date object (right object) and false if not. Assume that all objects of class Date are valid, i.e. month is between 1 and 12, inclusive; day contains an appropriate day for the given month, and year can be anything. You don't need to demonstrate calling these operators.Write a class named Person with data attributes for a person’s name, address, and telephonenumber. Next, write a class named Customer that is a subclass of the Person class. TheCustomer class should have a data attribute for a customer number, and a Boolean data attributeindicating whether the customer wishes to be on a mailing list. Demonstrate an instance of theCustomer class in a simple program.
- Implement the Solver class. The point of the solver class is the solve method which takes a board/puzzle configuration represented as a 2D array of bytes and returns a byte array containing a minimal sequence of moves that will lead to the solved board. The 2D array of bytes is “triangular” and represents a valid board configuration. Namely, the 2D array has 5 rows (0 – 4) and the size of every row is 1 more than its index.The array contains one 0, five 1s, four 2s and five 3s. The solve method then returns an array of bytes representing a minimal sequence of moves that solves the puzzle. In other words, if the numbers from the returned array are used in order as inputs to the move method on the Board object representing the initial configuration, the resulting board configuration represents the solved board. If the input to the solve method is a board configuration that is already solved, then solution requires no moves and an array of size 0 must be returned. impliment the solver…Implement the Solver class.

Restructure this program according to the model/view pattern so that these areas of responsibility are assigned to separate sets of classes. The program should include a Doctor class with an interface that allows one to obtain a greeting, a signoff message, and a reply to a patient’s string. To implement the greeting, define a method named greeting for the Doctor class. To implement the signoff message, define a method named farewell for the Doctor class. Both greeting and farewell should return a string with a greeting or farewell message respectively. The reply function is defined for you, it should be added as a method for the Doctor class. The rest of the program, in a separate main program module, handles the user’s interactions with the Doctor object. Develop this program with a terminal-based user interface. Note: The program should output in the…
