Welcome to my State Design Pattern Tutorial! I explain how the state pattern is used by using it to simulate an ATM machine.

I explain how you come to decide on the different states. I then show you how to design the interface that each state will use. We think about the methods that are needed for every class that implements the interface then.

All the steps are looked at from many directions and the code above will fill in the gaps.

Welcome to my Proxy Design Pattern Tutorial! The Proxy design pattern limits access to just the methods you want made accessible in another class.

It can be used for security reasons, because an Object is intensive to create, or is accessed from a remote location. You can think of it as a gate keeper that blocks access to another Object. I demonstrate how the proxy pattern works using some code used in my state design pattern tutorial. You may want to check that tutorial out before proceeding.

Welcome to my Object Oriented Design Tutorial! I cover a ton of things in the video below.

The goal of this tutorial is to teach you how to create excellent OO designs. In this tutorial, I start off with a programming idea and walk you through the process of creating a Use Case, Object Model, Sequence Diagram and Class Diagram.

Welcome to my Template Method Design Pattern Tutorial. It is an extremely easy design pattern to understand and use.

With this pattern, you define a method (algorithm) in an abstract class. It contains both abstract methods and non-abstract methods. The subclasses that extend this abstract class then override those methods that don't make sense for them to use in the default way.

It may sound complicated, but it definitely isn't. It is also extremely useful. Look at the code above to get a complete understanding quickly.
