Java AbstractQueue is an abstract class that implements the Java Queue interface and provides skeletal implementations for most of the methods in the Queue interface. It is typically extended by other classes that provide concrete implementations for specific types of queues, such as Java LinkedList or Java PriorityQueue. Introduced in Java 2004 with Java 5, AbstractQueue allows developers to create custom queue behaviors while inheriting basic queue functionality.
