Java LinkedList.removeFirst() is a method in the Java LinkedList class that removes and returns the first element of the list. It throws a Java NoSuchElementException if the list is empty. Introduced in Java 1997 with Java 1.2, removeFirst() is often used in deque or queue operations where elements need to be removed from the head of the list in a thread-safe or sequential manner.
