Java Classes and Objects

Object Oriented programming is advantageous because it allows the programmer to think in terms of the way people think of the real world, in terms of Objects like employees, airplanes, and homes for example. In procedural programming, the programmer tends to think more in terms of procedures or functions. In Object-Oriented Programming in a language such as Java, Classes and Objects are often used interchangeably but there is a distinction between the two. A class is a blueprint for objects. There often is a direct correlation between objects in the real world and objects in the programming realm. A Car Dealership may need to track many different cars that arrive and are sold from a lot. An inventory program may be used to represent each actual car as an object in the program. An automobile may come in many different makes, colors, and models, but each car object has those same attributes. A Car class then contains the common attributes all cars have; color, make and model. When an Object of a Car is made from the Car class, it is then assigned a specific color, such as a red Nissan Sentra or a blue Toyota Camry. Many Car objects can be made from that one Car class definition, or blueprint. One could then create an inventory application for the Car dealership with all of the colors, makes and models of cars in the dealership.In this project you will create an application that defines a Car class and create one to many Car objects.

Create child classes that inherit from the abstract class and implement the method.
Create a list of objects of the child classes and call the method on each object.

Practice creating and using interfaces in Python

Show steps

Interfaces are essential for loosely coupled code; practicing with them will enhance your coding skills.

Show steps

Create an interface with a method that must be implemented in its child classes.
Create child classes that implement the interface.
Create a list of objects of the child classes and call the method on each object.

Practice creating and using decorators in Python

Show steps

Decorators can enhance your code's functionality; practicing with them will make you a more effective coder.

Show steps

Create a decorator that prints a message before and after the execution of a function.
Use the decorator on a function and call the function.

Practice creating and using generators in Python

Show steps

Generators are a powerful tool for memory-efficient iteration; practicing with them will boost your programming skills.

Show steps

Create a generator that yields a sequence of numbers.
Use a for loop to iterate over the generator.

Practice creating and using iterators in Python

Show steps

Iterators are essential for efficient iteration; practicing with them will refine your programming skills.

Show steps
