Please code in python Create a program with two classes – the person class and the student The person class has the following properties: first name (first_name), last name (last_name) street address (address) city (city) zip code (zip) The class has the following methods: get_full_name, which returns the full name of a person get_full_address, which return greeting, returns a greeting message. The class should provide accessor and mutator for each property The class should override the __str__ method to return the state of the object. Create a child class called student which has a property named graduation year (graduation_year) and major. Provide accessor and mutator for each property of its own It inherits all the properties and methods of the person parent class as well. Create a test program that Create an object of the person class and print the full name of a person. Create an object of the person class and print…

Create a class of type student .Members will include: name, gpa, rank (year) Make sure all data is private and all functions are public. Write member functions to:Set or initialize the dataRetrieve the data (get’em and set’em )Announce names of students who are eligible for a scholarship (those who have a GPA of 3.0 or higher)The program will declare at least two objects (pupils) of your new class and test each of the functions (OR if you would like to try your hand at vectors, create them dynamically- this may require a little research/review on your part).

JAVA Programming Problem 3 - Book A Book has such properties as title, author, and numberOfPages. A Volume will have properties such as volumeName, numberOfBooks, and an array of book objects (Book [ ]). You are required to develop the Book and Volume classes, then write an application (DemoVolume) to test your classes. The directions below will give assistance. Create a class called Book with the following properties using appropriate data types: Title, Author, numberOfPages, Create a second class called Volume with the following properties using appropriate data types: volumeName, numberOfBooks and Book [ ]. The Book [ ] contains an array of book objects. Directions Create a class called Book with the following properties using appropriate data types: Title, Author, numberOfPages, The only methods necessary in the Book class, for this exercise, are the constructor and a toString(). Create a second class called Volume with the following properties using appropriate data types:…

6. Patient Charges Write a class named Patient that has attributes for the following data: • First name, middle name, and last name • Address, city, state, and ZIP code • Phone number ● The Patient class's init__ method should accept an argument for each attribute. The Name and phone number of emergency contact Patient class should also have accessor and mutator methods for each attribute. Next, write a class named Procedure that represents a medical procedure that has been performed on a patient. The Procedure class should have attributes for the following data: • Name of the procedure • Date of the procedure • Name of the practitioner who performed the procedure • Charges for the procedure 107 The Procedure class's __init__ method should accept an argument for each attribute. The Procedure class should also have accessor and mutator methods for each attribute Next, write a program that creates an instance of the Patient class, initialized with sample data. Then, create three…
