Top 5 Books to Learn Concurrent Programming and Multithreading in Java - Best, Must Read

Books are essential to learning something new, and despite being in the electronic age, where books have lost some shine to the internet and blogs, I still read and recommend them to get complete and authoritative knowledge on any topic, like concurrent programming. In this article, I will share five best books to learn concurrent programming in Java. These books cover basics, starting from how to create and start a thread, parallel programming, concurrency design patterns, an advantage of concurrency and of course pitfalls, issues, and problems introduced due to multithreading. Learning concurrent programming is a difficult task, not even in Java but also in other languages like C++ or modern days JVM languages like Groovy, Scala, Closure, and JRuby.

How to avoid deadlock in Java?

How to avoid deadlock in Java? Is one of the popular Java interview question and flavor of the season for multi-threading, asked mostly at a senior level with lots of follow up questions. Even though the problem looks very basic but most of the Java developers get stuck once you start going deep. Interview questions start with, "What is a deadlock?" The answer is simple when two or more threads are waiting for each other to release the resource they need (lock) and get stuck for infinite time, the situation is called deadlock. It will only happen in the case of multitasking or multi-threading.

How Thread, Code and Data Works Together- Story of a Multi-threading Program in Java

There are certain things, which you don't learn in academics or training class, you develop those understanding after few years of work experience, and then you realize, it was very basic, how come I had missed that all those years. Understanding of how a multi-threaded Java program executes is one of such things. You definitely have heard about threads, how to start a thread, how to stop a thread, definitions like its independent path of execution, all funky libraries to deal with inter-thread communication, yet when it comes to debugging a multithreaded Java program, you struggle.

How to Remove a Key, Value, or Entry from an HashMap in Java 8 - Example Tutorial

In the last article, I have shown how to remove key/value pairs from a map in Java-based upon some conditions like remove all entries where values are greater than some values. I have told you that you must use the Iterator's remove() method for removing mapping while iteration to avoid ConcurrentModificationException, but that's not required anymore in Java 8. From JDK 8 onwards, you can selectively remove mapping without iterating over Map. The JDK 8 API has added several new methods to existing interfaces e.g. java.util.Collection, java.util.Map, Comparator, etc because the interface can now contain concrete methods in the form of static and default methods.
