LinkedBlockingDeque in Java is an implementation of BlockingDeque interface and is part of java.util.concurrent package. LinkedBlockingDeque, just like LinkedBlockingQueue, is an optionally-bounded blocking queue which means the capacity for the queue can be specified thus making it bounded or it can be left unspecified in which case capacity of the…
