Final answer:
A custom Linked List in Java named 'My API' should mimic the Java Standard Library's LinkedList with similar add, remove, and get operations, but may have a unique internal implementation to achieve the same outward behavior.
Step-by-step explanation:
The task of creating a custom Linked List in Java involves mimicking the behavior of the Java Standard Library's LinkedList class. This custom data structure, referred to here as My API, should provide the same outcomes as the native Java API by implementing the essential operations such as add, remove, and get methods that function in a similar manner. To achieve this, one needs to first understand the basics of a Linked List, which is a sequence of nodes where each node contains data and a reference to the next node in the sequence.
A simple implementation begins with defining the node structure. This would involve a Node class that has two attributes: the data itself and a reference to the next node. The Linked List class itself should maintain a reference to the head node (the start of the list) and possibly a tail node (the end of the list) for efficient operations.
For the add method, the My API should insert a new node either at the end of the list, making it the new tail, or insert it at a specific position. Consequently, the remove method would locate and unlink a node from the list at a certain index or remove a specific object if exists. The get method retrieves the data of the node at a given index without alteration.
Exception handling mirrors that of the Java API; for example, the method attempts to remove an element from an empty list throw a NoSuchElementException. Additionally, browse and search features are crucial for the utility of the list. For example, implementing an iterator can provide an efficient way to navigate through the elements. When the Linked List is correctly implemented, the user should not notice any difference in basic list behavior when compared to using Java's own LinkedList class.
