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 →

Java virtual thread is a new feature available from JDK 19. It has potential to improve an application’s availability, throughput and code quality on top of reducing memory consumption. If you are interested in learning more about Java virtual thread,... Continue Reading →
When a method is synchronized, only one thread can enter that object's method at a given point in time. If any other thread tries to enter the synchronized method, it will NOT be allowed to enter. It will be put... Continue Reading →
Java developers tend to use 'java.util.UUID#randomUUID()' API, to generate a UUID (Universally Unique Identifier) number (i.e., 'b8bbcbed-ca07-490c-8711-5118ee0af2f9'). Under certain circumstances, using this API can affect your application’s availability. Let’s discuss this API in this post with a real-world example. Video:... Continue Reading →
