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.

Things are being built upon cloud foundations to transform organizations. This CEO Power Panel at 15th Cloud Expo, moderated by Roger Strukhoff, Cloud Expo and @ThingsExpo conference chair, will address the big issues involving these technologies and, more important, the results they will achieve. How important are public, private, and hybrid cloud to the enterprise? How does one define Big Data? And how is the IoT tying all this together?
The Internet of Things (IoT) is going to require a new way of thinking and of developing software for speed, security and innovation. This requires IT leaders to balance business as usual while anticipating for the next market and technology trends. Cloud provides the right IT asset portfolio to help today’s IT leaders manage the old and prepare for the new. Today the cloud conversation is evolving from private and public to hybrid. This session will provide use cases and insights to reinforce the value of the network in helping organizations to maximize their company’s cloud experience.
TechCrunch reported that "Berlin-based relayr, maker of the WunderBar, an Internet of Things (IoT) hardware dev kit which resembles a chunky chocolate bar, has closed a $2.3 million seed round, from unnamed U.S. and Switzerland-based investors. The startup had previously raised a €250,000 friend and family round, and had been on track to close a €500,000 seed earlier this year — but received a higher funding offer from a different set of investors, which is the $2.3M round it’s reporting."
The Industrial Internet revolution is now underway, enabled by connected machines and billions of devices that communicate and collaborate. The massive amounts of Big Data requiring real-time analysis is flooding legacy IT systems and giving way to cloud environments that can handle the unpredictable workloads. Yet many barriers remain until we can fully realize the opportunities and benefits from the convergence of machines and devices with Big Data and the cloud, including interoperability, data security and privacy.
All major researchers estimate there will be tens of billions devices - computers, smartphones, tablets, and sensors - connected to the Internet by 2020. This number will continue to grow at a rapid pace for the next several decades. Over the summer Gartner released its much anticipated annual Hype Cycle report and the big news is that Internet of Things has now replaced Big Data as the most hyped technology. Indeed, we're hearing more and more about this fascinating new technological paradigm. Every other IT news item seems to be about IoT and its implications on the future of digital busines...

This Internet of Nouns trend is still in the early stages and many of our already connected gadgets do provide human benefits over the typical infotainment. Internet of Things or IoT. You know, where everyday objects have software, chips, and sensors to capture data and report back. Household items like refrigerators, toilets and thermostats along with clothing, cars and soon, the entire home will be connected. Many of these devices provide actionable data - or just fun entertainment - so people can make decisions about whatever is being monitored. It can also help save lives.
