Java AbstractQueue.size() is a method in the Java AbstractQueue class that returns the number of elements in the queue. It provides the current size of the queue, which can be used to determine if the queue is empty or how many elements need to be processed. Introduced in Java 2004 with Java 5, size() is essential for managing the state of a queue and performing conditional operations based on its size.
