This updated edition of Programming Android focuses on the knowledge and developer priorities that are essential for successful Android development projects. This is a book I am recommending to all my readers of The Java Specialists' Newsletter, because it is interesting, useful, and relevant to the problems facing Java developers today. Read More: Is java concurrency really that simple? The 1 point to take from this book is to avoid mutable data structures at all costs. Clever tricks may make code faster, but they make it more likely to be wrong and harder to maintain. Code executed by multiple threads accessing shared data need special attention. In fact, I would admit that before reading that book, I have lots of misconceptions about many essential multi-threading and concurrency concepts e.
The Java Concurrency in Practice book teach those concepts to many Java programmer. As an intermediate Java programmer that has yet to learn how to use concurrency, I now see that perhaps it is a good idea to brush off the concepts and delve into Java 8 lambda expressions rather than train methodically to master concurrency and its best practices as introduced in Java 1. Easier said than done of course, but much easier than lock-based concurrency. While one sentence is more than enough for an expert, event a vivid and willingfull learner could feel like being left alone. Now this same team provides the best explanation yet of these new features, and of concurrency in general. This book mixes general concurrency background and advice with Java specific advice with advice applicable to only certain versions of Every programming language needs to have a book like Java Concurrency in Practice.
With Safari, you learn the way you learn best. They are so specific to a particular version of a particular language that any small change renders them useless. The emoticons it used to show the bad practice before introducing the good and right way to do helped a lot not only to correct the misconception many Java developer had before but to sow the seed of right information pertaining to multi-threading and concurrency among Java developers. One of my reader Shobhit asked this question on my blog post about for intermediate programmers - part1. If you're experienced with Java or Objective-C, you'll gain the knowledge necessary for building well-engineered applications. Concurrent applications usually have more complex design in comparison to single threaded application. However, developing, testing, and debugging multithreaded programs can still be very difficult; it is all too easy to create concurrent programs that appear to work, but fail when it matters most: in production, under heavy load.
Basically, you had threads and you had synchronized methods. The very first class, you will need to make a java class concurrent, is class. They were not made aware of that how volatile can guarantee visibility of what was done by one thread prior to accessing volatile variable to other thread etc. Click Download or Read Online button to get java-concurrency-in-practice-epub book now. I have seen many programmers who simply wasn't able to visualize how multiple threads are interacting with the same piece of code with different data. Concurrency enable a program to achieve high performance and throughput by utilizing the untapped capabilities of underlying operating system and machine hardware.
The fact is that we never were aware of any good material which would help us to prepare and learn to build thread safe, concurrent applications. Highlights include: New coverage of generics, enums, annotations, autoboxing, the for-each loop, varargs, concurrency utilities, and much more Updated techniques and best practices on classic topics, including objects, classes, libraries, methods, and serialization How to avoid the traps and pitfalls of commonly misunderstood subtleties of the language Focus on the language and its most fundamental libraries: java. Many programmers even with 4 to 5 years of experience in Java didn't understand , what they know is that when you use a volatile variable it always check the value from main memory while comparing, which is the truth but not complete. But quite a few of us have tried to venture into learning the nuisance of multi-threading, concurrency and never got close to even attempting to learn. Heinz Kabutz' can be used to keep yourself up-to-date. Book wonderfully covers ins and outs of concurrent programming in Java. Errors arising from incorrect thread synchronization are very hard to detect, reproduce and fix.
Part Two delves into the Android framework, focusing on user interface and graphics class hierarchies, concurrency, and databases. Throughout the book the refere Book wonderfully covers ins and outs of concurrent programming in Java. It also goes on to explain why most concurrent applications are incorrectly written in Java and the common mistakes made by Java programmers which result in multi-threading issues like race conditions, deadlock, livelock, memory interference and simply incorrect calculation. Complete descriptions of new language and platform features are highlighted and integrated with insightful explanations of advanced Java programming techniques. For anyone exposed to the pre-Java5 concurrency support implicit locking and volatile this is an eye-opener. They usually shows up in higher environments like production, and replicating the error is sometimes not possible in lower environments. That is not the case with Java Concurrency in Practice.
Also, lambda expression is independent of concurrency, you can still learn how to use that while learning concurrency and multithreading fundamentals. It then moves on to defining basic concepts such as thread safety, atomicity, locking, liveness, visibility, and publication. Many old Java idioms are no longer required and new features like lambda expressions will increase programmer productivity, but navigating these changes can be challenging. I feel like I have a reasonable background with concurrency in theory although not in practice. Brian's book is the most readable on the topic of threading and concurrency in Java, and deals with this difficult subject with a wonderful hands-on approach.
You also got the stream and parallel stream which allows developers to take advantage of concurrency without coding it. This book covers: Basic concepts of concurrency and thread safety Techniques for building and composing thread-safe classes Using the concurrency building blocks in java. Java Concurrency in Practice provides you with the concepts. Thirdly, there are no exercises in the book, so there is no virtually no way to check the understanding of the material. It was quiet easy to review this book, because i try to re-read it every year and it had became a necessity for me. It introduces you to all new changes in Java 8 and not only teaches you how to use them in your day-to-day task but also explains the motivation behind them to understand the bigger picture. Heinz KabutzThe Java Specialists' Designed for serious programmers, this reliable, unbiased, no-nonsense tutorial illuminates advanced Java language and library features with thoroughly tested code examples.
Even though Java Concurrency in Practice in its current state doesn't cover all these important concepts and tools, it's still an invaluable book to learn the fundamentals of, and tools supported by Java programming language. When this book came first in 2006, Java world was still not sure of about new concurrency changes made in Java 1. Bruce believes Java is abandoning its base, and conditions are ripe for an alternative to emerge. He closes with an evaluation of the most popular and important programming languages, and their future role in a world beyond Java. Even as other languages become primary, there are still many parts of the book that will be worth rereading but not all, which is why I say every language needs its own equivalent of this book. Now this same team provides the best explanation yet of these new features, and of concurrency in general.
