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.

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:…
