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’.
