This method should display values of two data fields contained within the object that is passed to the method. Make-up your own method definition that meets these requirements.

Java Code Now that we've discussed how object inheritance works, we've covered all of the basic principles of object-oriented design. You should now be familiar with two different methodologies for creating programs: Structural/Procedural design: A program is split into one or more functions, which can all be in the same file or in different files. The code runs sequentially, using no dynamic binding. Code and data are kept separate. This is how you first learned to write programs, before you knew how to create classes and objects. Object-Oriented design: A program is split into different groupings of data and code called objects. The program runs by creating interactions between objects, which may involve dynamic binding (polymorphism) to decide what functions to call at runtime. The data and code are inseparable from each other, and data is often hidden to prevent unwanted access by unknown code. This is how we've learned to write programs in this course. state what you believe are…

The method add is called within the code for the methods __init__ and __add__ in the AbstractBag class, but it is not defined in that class. To which class does this method belong, and how does Python locate its implementation? *Python

When an interface is implemented, why are all of its methods need to be implemented at the same time?

A chiropractor needs a JAVA application that keeps track of the appointments she’s made with her clients and keeps track of their outstanding balances. As the applications developer, you determined that Client and Appointment classes are needed.   Develop the class file java. Make sure that the class stores the client’s name, and the outstanding balance. Client objects should have a method to increase its balance whenever the patient completes (or misses) an appointment and a method to reduce the balance when a payment is made. (Negative balances are OK). Include the appropriate constructor and accessor methods.   The class filejava. stores a reference to the appropriate Client object, the (future) date/time of the appointment, and the total cost of the appointment. You may want to design a PastAppointment subclass that keeps track of whether the appointment was “cancelled” (if the patient called with sufficient advanced notice), or “missed” (if the patient missed the appointment),…

Written in Python  It should have an init method that takes two values and uses them to initialize the data members. It should have a get_age method. Docstrings for modules, functions, classes, and methods

True or False? Interface can be used to store a common method implementation.

Why is it necessary to implement all of the methods defined by an interface?

read carefully. object must be passed to method not variables
