Book Review: Java Coding Guidelines

Part of the SEI Series in Software Engineering

Although this book is written for the Java programmer, I would recommend reading it to any .NET or iOS developer as well. It is a must read for the Java developer, but is also a valuable read for developers of other languages because the guidelines are often built around a programmer's intent.

No matter what language you use most, many of the intentions that are targeted by the guidelines are the same. Do I wish there was a C# and Objective-C version of this book? Heck Yeah!!! But, one of the things that helped get to a deeper understanding of the guidelines was thinking about where and how they apply to C# and Objective-C. There is Secure Coding in C and C++ (Second Edition) and The CERT C Secure Coding Standard which are both great too.

The guidelines are broken down by chapter. The book also has an appendix that lists all 75 guidelines and whether or not the guideline is applicable to Android development. I have listed the chapters below. I have also included an overview of what the guidelines in the chapters are targeting as described in the introduction to the chapters.

Chapter 1. Security
1. Dealing with sensitive data
2. Avoiding common injection attacks
3. Language features that can be misused to compromise security
4. Details of Java’s fine-grained security mechanism

Chapter 2. Defensive Programming
The guidelines in this chapter address areas of the Java language that can help to constrain the effect of an error or help to recover from an error. A good overall principle for defensive programming is simplicity. If a construct turns out to be complicated to implement, consider redesigning or refactoring it to reduce the complexity.

Chapter 3. Reliability
1. Guidelines that help reduce errors, and are consequently important for developing reliable Java code.
2. Guidelines that contain specific Java coding recommendations to improve software reliability

Chapter 4. Program Understandability
Program understandability is the ease with which the program can be understood—that is, the ability to determine what a program does and how it works by reading its source code and accompanying documentation. Some guidelines in this chapter are stylistic in nature; they will help a Java programmer to write clearer, more readable code. Failure to follow these guidelines could result in obscure code and design defects.

Chapter 5. Programmer Misconceptions
1. Misconceptions about Java APIs and language features
2. Assumptions and ambiguity-laced programs
3. Situations in which the programmer wanted to do one thing but ended up doing another

Appendix A: Android
This appendix describes the applicability of the guidelines in this book to developing Java apps for the Android platform.

I really liked the way the chapter on defensive programming brought the goal of simplicity to the forefront. One of the hardest things to do is maintain simplicity when coding. Often times getting through very complex situations ends with a lot of the code being in a state where it can be refactored into much cleaner code.

I find one of the biggest mistakes programmers make is saying they will come back to it later and clean it up. They honestly have the best intention of doing that and sometimes even come back to do that. When they do they realize that the big ball of mud they made just getting the problem resolved will take too much time to relearn. What they had done two weeks prior gets left alone with the thought, it isn't broke, so I'll just leave it. Cleaning it up while it is fresh in your head is what needs to become a habit, otherwise never cleaning up will become your habit.

One of the really nice features of the book is that the author's include references to the rules that apply from The CERT Oracle Secure Coding Standard for Java. All of the rules are available on line- just google "CERT Oracle Secure Coding Standard for Java". Once there you just plug the code used in the book into the search and you're taken to the rule. The rule has more information and more code samples.

They also include references back to the online The Java Virtual Machine Specification- Java SE 7 Edition. Having these references really helps you get any additional information to help you fully understand the topic at hand.

Another thing I really like is that they show tons of noncompliant code examples and compliant solutions. It really helps to have the examples along with the explanations.

In the beginning of the book the authors say "While primarily designed for building reliable and secure systems, these guidelines are also useful for achieving other quality attributes such as safety, dependability, robustness, availability, and maintainability." I must agree and say that they have really provided a treasure chest of wisdom in this book. Following the guidelines in this book will go a long way in helping you achieve the quality attributes listed above in your architecture.

All in all I highly recommend this book to all Java developers. It is a must read for you. I also recommend to developers of other languages that want to gain new insight into guidelines that they can apply in their language of choice.

The Internet of Things will challenge the status quo of how IT and development organizations operate. Or will it? Certainly the fog layer of IoT requires special insights about data ontology, security and transactional integrity. But the developmental challenges are the same: People, Process and Platform and how we integrate our thinking to solve complicated problems. In his session at 19th Cloud Expo, Craig Sproule, CEO of Metavine, will demonstrate how to move beyond today's coding paradigm ...
Digitization is driving a fundamental change in society that is transforming the way businesses work with their customers, their supply chains and their people. Digital transformation leverages DevOps best practices, such as Agile Parallel Development, Continuous Delivery and Agile Operations to capitalize on opportunities and create competitive differentiation in the application economy.

With the rise of Docker, Kubernetes, and other container technologies, the growth of microservices has skyrocketed among dev teams looking to innovate on a faster release cycle. This has enabled teams to finally realize their DevOps goals to ship and iterate quickly in a continuous delivery model. Why containers are growing in popularity is no surprise — they’re extremely easy to spin up or down, but come with an unforeseen issue. However, without the right foresight, DevOps and IT teams may lo...
In his general session at 18th Cloud Expo, Lee Atchison, Principal Cloud Architect and Advocate at New Relic, discussed cloud as a ‘better data center’ and how it adds new capacity (faster) and improves application availability (redundancy). The cloud is a ‘Dynamic Tool for Dynamic Apps’ and resource allocation is an integral part of your application architecture, so use only the resources you need and allocate /de-allocate resources on the fly.
Your business relies on your applications and your employees to stay in business. Whether you develop apps or manage business critical apps that help fuel your business, what happens when users experience sluggish performance? You and all technical teams across the organization – application, network, operations, among others, as well as, those outside the organization, like ISPs and third-party providers – are called in to solve the problem.
Information technology is an industry that has always experienced change, and the dramatic change sweeping across the industry today could not be truthfully described as the first time we've seen such widespread change impacting customer investments. However, the rate of the change, and the potential outcomes from today's digital transformation has the distinct potential to separate the industry into two camps: Organizations that see the change coming, embrace it, and successful leverage it; and...
The Jevons Paradox suggests that when technological advances increase efficiency of a resource, it results in an overall increase in consumption. Writing on the increased use of coal as a result of technological improvements, 19th-century economist William Stanley Jevons found that these improvements led to the development of new ways to utilize coal. In his session at 19th Cloud Expo, Mark Thiele, Chief Strategy Officer for Apcera, will compare the Jevons Paradox to modern-day enterprise IT, e...
As applications are promoted from the development environment to the CI or the QA environment and then into the production environment, it is very common for the configuration settings to be changed as the code is promoted. For example, the settings for the database connection pools are typically lower in development environment than the QA/Load Testing environment. The primary reason for the existence of the configuration setting differences is to enhance application performance. However, occas...

Analysis of 25,000 applications reveals 6.8% of packages/components used included known defects. Organizations standardizing on components between 2 - 3 years of age can decrease defect rates substantially. Open source and third-party packages/components live at the heart of high velocity software development organizations. Today, an average of 106 packages/components comprise 80 - 90% of a modern application, yet few organizations have visibility into what components are used where.
Throughout history, various leaders have risen up and tried to unify the world by conquest. Fortunately, none of their plans have succeeded.
