Java AbstractQueue.peek() is a method in the Java AbstractQueue class that retrieves, but does not remove, the head of the queue, or returns null if the queue is empty. This method is commonly used to view the first element in a queue without modifying it. Introduced in Java 2004 with Java 5, peek() is often used in scenarios where you need to inspect the front of the queue without altering the underlying data structure.
