The <code>java.util.concurrent.ConcurrentLinkedQueue</code> class extends {{java|java.util.AbstractQueue}}, Hence, .<code>ConcurrentLinkedQueue</code> implements the {{java|java.util.Queue}} interface.{{sfn|Goetz|Peierls|Bloch|Bowbeer|2006|loc=§5.2 Concurrent collections|pp=84-85}}
The <code>{{java|ConcurrentLinkedQueue</code>}} class is a thread-safe collection, since for any an element placed inside a {{java|ConcurrentLinkedQueue}}, the Java Collection Library guarantees that the element is ''safely published'' by allowing any thread to get the element from the collection.{{sfn|Goetz|Peierls|Bloch|Bowbeer|2006|loc=§3.5.3 Safe publication idioms|pp=52-53}} An object is said to be ''safely published'' if the object's state is made visible to all other thread at the same point in time.{{sfn|Goetz|Peierls|Bloch|Bowbeer|2006|loc=§3.5.3 Safe publication idioms|pp=52-53}} Safe publication usually requires synchronization of the publishing and consuming threads.{{sfn|Goetz|Peierls|Bloch|Bowbeer|2006|loc=§3.5.3 Safe publication idioms|pp=52-53}}
