I am going to develop a TCP server. In this case I have to do queuing. So currently I'm using List as my queue. But java providing queue object. I want to know what is the best object for do queuing process.
Java has a Queue interface. You can take a look for yourself which classes in the standard API implement it that fit your needs. For a simple Queue, I can recommend ArrayDeque. However, you may also want to take a look at classes that implement BlockingQueue or PriorityQueue, if you need their specific semantics.
