The contains() method of List interface in Java is used for checking if the specified element exists in the given list or not . … Return Value: It returns true if the specified element is found in the list else it returns false.

Lists (like Java arrays) are zero based . Note that these operations may execute in time proportional to the index value for some implementations (the LinkedList class, for example). Thus, iterating over the elements in a list is typically preferable to indexing through it if the caller does not know the implementation.
