Block read operation of ConcurrentHashMap in multithreaded environment
Block read operation of ConcurrentHashMap in multithreaded environment I have a ConcurrentHashMap. When thread t1 will do a write operation on it then I want thread t2 cannot do any read operation on it. The read operation should then be blocked. How will I achieve this?
