Java interview questions: – What are blocking Queues?

Following classes are blocking Queues in Java interview questions.

The java.util.concurrent package contains a set of synchronized Queue interfaces and classes. Blocking Queue extends Queue with operations that wait for the queue to become nonempty when retrieving an element and for space to become available in the queue when storing an element. This interface is implemented by the following classes:-

  • Linked Blocking Queue — an optionally bounded FIFO blocking queue backed by linked nodes
  • Array Blocking Queue — a bounded FIFO blocking queue backed by an array
  • Priority Blocking Queue — an unbounded blocking priority queue backed by a heap
  • Delay Queue — a time-based scheduling queue backed by a heap
  • Synchronous Queue — a simple rendezvous mechanism that uses the Blocking Queue interface
