Java Design Patterns Book

In this article, we will look at some fundamental concepts of Java Design Pattern and then most popular Java Design Patterns Book. Keep in mind that there is always a possibility to improve your software. If you have a good catch on Java Design Patterns, you will always be able to find a possibility to improve your software.

Let’s first talk about the complications we may face if we haven’t ever read any Java Design Patterns book. If I ask you to list down all the Design Patterns used in your current project module, would you be able to accomplish it? If yes, you have read a book and you are here to sharpen your skills in Design Patterns. Let’s assume your answer is not, then you need to go through a good Java design patterns book accordingly and start enhancing your skills.

What is a Design Pattern in Java?

Before getting to know about Design Pattern in Java, let’s discuss what is a Software Design Pattern? A software Design Pattern is a description or guideline to solve a problem that occurs repeatedly while developing a software Application. Some people in the industry also call it a template as it solves the problems while developing the application. When we talk about these types of solutions to recurring problems in Java language, they become ‘Design Patterns in Java’ or ‘Java Design Patterns’.

It was 21 October 1994, when four authors Erich Gamma, Richard Helm, Ralph Johnson and John Vlissides, with a foreword by Grady Booch, published a book titled as Design Patterns – Elements of Reusable Object-Oriented Software which launched the concept of Design Pattern in Software design. These four authors are altogether known as Gang of Four (GOF). We have kept this book in the first place on our list.

What is the structure of a Design Pattern?

We can describe the structure of a Design Pattern in following pieces of the action.

Pattern name : describes the name of the pattern
Intent : describes what the pattern does
Motivation : Describes the example of a problem and it’s solution
Applicability : Provides the list of situations where the pattern is applicable
Structure : Represents the diagrams of classes and objects to illustrate the pattern
Participants : Provides the description of classes and objects which participate in the design
Collaborations : Provides the description of the participant’s responsibilities and their collaborations
Consequences : Provides the benefits of using the pattern
Also, Known as : Describes the other popular name or synonyms of the pattern

What are the benefits of reading a book on Design Pattern?

Here, I want to point out one thing that Design Patterns are not closely related to Java Application Design. They are useful to us while we think about a solution to a problem during project development. Some of you may not agree with me, but it’s a truth. Believe me or not, if you are strong in design patterns, you will complete your development earlier than the expected time and number of bugs will also be very negligible. In contrast, if you are weak in design patterns, you will face a lot of problems while developing, even sometimes you may need to modify your code from the beginning, that can result in pain & frustration.

If you are strong in Java Design Patterns, your confidence level will also be high because design patterns itself provide you solutions for many common use cases. Also, you will never feel low while developing a project. Even you will be able to suggest a better solution to a problem instead of the existing one. Moreover, apart from finding a solution to a problem, Design Patterns will help you in fixing performance and memory related issues.

If you are planning to apply for a job as an experienced developer, keep in mind that your interview will not be completed without Design Patterns questions. For Singleton Design Pattern, you may refer our article on ‘Singleton Design Pattern In Java With All Scenarios‘ which is approximately sufficient to provide all answers of Singleton Design Pattern’s questions. Furthermore, in order to learn all Design Patterns, you may also visit our separate article on Design Patterns in Java.

Design Pattern Books

We are going to provide list of Design Pattern Books with some description what we experienced after reading them.

1) Design Patterns : Elements of Reusable Object-Oriented Software 

As aforementioned, the authors of this book are also the founders of Design Pattern. Needless to say, how much popularity this book has. Even while reading this book, you will completely understand why we need to explore the Design Patterns and how a Design Pattern makes developers life easy. The book consists of mainly two parts. The first two chapters describe the capabilities and drawback of object-oriented programming. Remaining chapters describe 23 classic software design patterns. However, the book incorporates examples in C++ and Smalltalk but a Java professional can easily understand the concepts from the example. In order to understand the in & out of the Design Patterns, this book is the best.

2) Head First Design Patterns (Java Design Patterns Book)

Head First Design Patterns are completely written in Java language. Moreover, the latest version of this book also includes the examples as per Java 8 language features. Instead of putting text-heavy approach, this book uses the visually rich format designs in the texts and pics as the way your brain works efficiently. All design patterns in this book start with a real-life example to clearly understand the problem and then describe the various approaches to fix the problem. Finally, it concludes with the best approach to solve the problem. Each Chapter in this book is designed based on the similarities in patterns. Suppose that two Design Patterns have some kind of similarities such as similar in behavior or problem, then they are kept in the same chapter. Moreover, at the end of each chapter questionnaire makes the book more engaging.

3) Design Patterns Explained : A New Perspective on Object-Oriented Design (Java Design Patterns Book)

The authors of this book are Alan Shalloway and James R. Trott. Instead of just explaining complex programming examples, book incorporates various analogies to make readers understand the concepts very easily. However, in my opinion, anyone having done OOP for a couple of years would benefit from it, including recent college graduates. Moreover, this book has one dedicated chapter to make you understand UML(Unified Modelling Language). Needless to say, how the UML plays an important role in a software design. Apart from that, it also covers object oriented design, some basic patterns, and commonality vs variability analysis. The earlier chapters present strategies for deriving design patterns using the principles of object oriented programming. The concepts presented in this book, provides the reader an ability to understand the ideology behind the patterns which improves the design skills.

4) Patterns in Java: A Catalog of Reusable Design Patterns Illustrated with UML: 1 (Java Design Patterns Book)

This book approximately covers the same principles as the ‘Design Patterns : Elements of Reusable Object-Oriented Software‘ written by GOF(Gamma, Helm, Johnson, Vlissides). However, it uses a bit simpler examples in Java. Many readers find it easier to read than GOF book. The positive point for Java developers is that the examples used in this book are in Java language. Hence, this book is good for those who want to have a flavor of Java in GOF’s book.

5) Patterns of Enterprise Application Architecture

This book covers most of the patterns used by all professional developer in detail with polished technical language. However, the examples in the book are in Java, C++ and C#. This book incorporates the architectural patterns with first 100 pages for people working in Enterprise projects. It book has comparatively less theory than many other design patterns’ books, but more practical in nature. All professionals who are in Architect or Designer role should go through this book at least once.

6) Software Architecture Design Patterns in Java (Java Design Patterns Book)

This book covers all the original Gang of Four patterns and also another 20 or so patterns with multiple examples for each, including few multithreading related patterns. Moreover, the explanations are very concise and to the point. The introduction to UML is very useful. It provides in-depth examples in Java, and guides readers by detailing when, why, and how to use specific patterns. This book concludes with a case study that brings several patterns together to illustrate how patterns are not applied in isolation, but integrate within domains to solve complicated problems.

7) JAVA DESIGN PATTERNS (Java Design Patterns Book)

This book illustrates all GOF design patterns in really simple and concise way with real-world examples. It contains 151 pages. All the examples in this book are in the Java language. The author has covered all the key points that are necessary to understand each design pattern easily. If you want to understand the ideology of each design pattern with examples in very less time, this book is the perfect. In contrast, if you want to become a master on design patterns this book is not for you. Hence, the other way is that you go through with this book to clear your basic concepts on all design patterns in a short period and then continue with the other book to become master of it.

9) Real World Java EE Patterns-Rethinking Best Practices

If you looking at Java EE Design Patterns book, this one is a good choice. If you already spent some time on developing Java EE applications, you can confidently go for it. Moreover, this book helps you to shift your thinking from J2EE to Java EE. Many of the old J2EE design patterns are outdated or have become anti-patterns in Java EE, but it’s difficult to find documentation that describes how the fundamental architecture has changed. The author has explained it thoroughly and clearly with real-world examples. While designing an application, you often come to a situation when you ask yourself ‘What is the right way to do it?’. You will find an elegant approach to find out the answers to such type of questions in this book.
