Java Design Patterns

Crucial to programming, Java design patterns remain significant as they function as toolkits for scripting problems and errors.  This eight-part lecture then provides a comprehensive discussion of these well-proved solutions. More so, this tutorial is presented so that course takers will achieve the following objectives:

• Learn how to implement several design patterns in Java
• Understand the technical usage of each design pattern
• Know the importance of their implementation
• Demonstrate Java design patterns’ best practices
• Acquire design pattern skills necessary to become an expert Java developer

Overview Design Patterns

The introduction discusses the fundamentals of design patterns, each of which is given thorough explanation. They are classified into two categories (Core Java and JEE), and their subcategories are also enumerated including creational, structural, and behavioral design patterns. Their importance and the best time to implement them are also discussed to create a holistic and solid structure for course takers.

Observer and Decorator Patterns

The lecture talks about observer and decorator patterns, two programming solutions that hold a level of relevance for cases of one-to-many relationships and keeping solid class methods.  This will see the implementation of both design patterns starting from creating classes to using them until the codes are ready for verification.

Factory and Singleton Patterns

This succeeding lecture thoroughly compares and contrasts the Factory and Singleton patterns, two solutions that prove to be effective for instance redirection, recreation, and retrieval. More so, their advantages are discussed simultaneously with their implementation.

Adapter and Façade Patterns

Considered as effective tools to resolve incompatibility and multiple components, the implementation of the Adapter and Façade patterns are discussed. Apart from this, they are put into deeper study so as to understand their importance, the best time of their implementation, and their advantages over other existing design patterns.

State and Proxy Patterns

Covered in this separate lesson are the theoretical and operational definitions, method of implementation, technicality, and function of the State and Proxy patterns. In addition to this, the latter’s subcategories are explored including remote, virtual, and protection proxies. Lastly, the use of Invocation Handler is demonstrated.

MVC and Builder Patterns

A separate section is dedicated for the discussion of Model-View-Controller and Builder patterns, creational solutions intended to implement systematized programming approach and divide pressing concerns of applications. Similar to the preceding lectures, this lesson makes use of comparison to provide an authoritative discussion of their relevance. Finally, their implementation in Java and their innate benefit are presented.

Prototype and Mediator Patterns

For those struggling to fix prototypal inheritance and creation, as well as sharing of subjects, this lecture will discuss two patterns that would resolve these issues. The Prototype and Mediator patterns are well-used solutions and their utilization are meticulously presented. In addition to this, their advanced usages are directly presented right after their basics.

Memento, Interpret, and Bridge Patterns

The final part of this Java design pattern series talks about the Memento, Interpret, and Bridge patterns.  They are given their separate explanation, all of which are equipped with introduction, implementation, and summary. Finally, their importance, relevance, and advantages are outlined so as to understand their principles and best practices.
