Java AbstractQueue.remove() is a method in the Java AbstractQueue class that removes and returns the head of the queue. If the queue is empty, it throws a Java NoSuchElementException. Introduced in Java 2004 with Java 5, remove() is used for queue manipulation where the removal of the front element is required, such as in task scheduling or data processing systems that follow a FIFO (first-in, first-out) order.
