Whether getting Java certified will help them to earn a better salary? or after becoming Java certified from Oracle will help them to get a Job. In this article, we will see what are the benefits of getting Java certified. I know higher income, better Job prospects, and a better chance of promotion is at the top of the benefits of becoming a certified Java professional, but this certification provides much more value than that.

Top 9 Java Programming Books - Best of lot, Must Read

These top Java programming books are some of the good books to learn Java and I would say some of them are simply best Java books ever published. Whenever a programmer starts learning Java programming language, the first question he asks is "Which book should I refer to learn Java?", or "What is the best book to learn Java for beginners?" or "Can you tell me some good books to learn Java?" .That itself says how important Java books are for programmers especially beginners.  Despite having so many free resources available in Java like tutorials, tips, blogs and code examples, Java books have their own place because of two reasons:
  • They are written by programmers who are authority in subject
  • They cover the subject with more details and explanation.

Is "Java Concurrency in Practice" still valid in the era of Java 8 and 10?

One of my reader Shobhit asked this question on my blog post about 12 must-reads advanced Java books for intermediate programmers - part1. I really like the question and thought that many Java programmers might have the same doubt whenever someone recommends them to read Java Concurrency in Practice. When this book came first in 2006, Java world was still not sure of about new concurrency changes made in Java 1.5, I think the first big attempt to improve Java's built-in support for multi-threading and concurrency. Many Java programmers were even not aware of new tools introduced in the API e.g. CountDownLatch, CyclicBarrier, ConcurrentHashMap and much more. The book offered them the seamless introduction of those tools and how they can use them to write high-performance concurrent Java applications.
