ConcurrentHashMap is used extensively in multi-threaded applications. The examples of multi-threaded applications are online gaming applications, chat applications, it adds the benefit of concurrency to the application. To make application more concurrent in nature, ConcurrentHashMap introduces a concept called ‘Parallelism’.... Continue Reading →
There are scopes of variable in Java programming language: a. Local variable b. Member variable (aka instance variable) c. Static variable (aka class variable) In this post, let's discuss an interesting type of variable: ThreadLocal and how it differs from... Continue Reading →
In our earlier post, we learnt that when a method is synchronized, only one thread will be allowed to enter the method. In this post, let's discuss the behavior of static synchronized methods. Video: To see the visual walk-through of this... Continue Reading →
