Java LinkedList.offerLast() is a method in the Java LinkedList class that inserts an element at the end of the list, returning true if the element was added successfully. It is a safer alternative to Java LinkedList.add() when you want to avoid potential exceptions and ensure that the list's structure remains intact. Introduced in Java 1997 with Java 1.2, offerLast() is commonly used for adding elements to a list in a thread-safe manner.
