I think you told read has a lock in concurrent hashmap that's not true , we have lock only on write operations. 😊 , Great job for this video really appreciate.

LibraryMangament system works well using concurrent hash map if you have hash key on starting letter of book name...if multiple theards tries to read and update rack info at a time so it will give error. just think about hash value.
