I was initially planning to write about LinkedList, but it seems that it's not well-represented in the market.
This led me to consider writing about LinkedBlockingQueue.java instead, which also implements the linked list data structure.

here is a real use of this implementation: https://github.com/PaytmLabs/cassandra/blob/master/src/java/org/apache/cassandra/db/ColumnFamilyStore.java#L89
