Linked-List in Java
Java’s LinkedList class is a versatile and commonly used data structure that implements the List and Deque interfaces while extending the AbstractSequentialList. Below is the list of operations performed on a java linked list,
|
Operations |
Syntax |
|---|---|
|
Declaration |
LinkedList<DataType> myLinkedList = new LinkedList<>(); |
|
Inserting X at Head |
myLinkedList.addFirst(X); |
|
Removing from Head |
myLinkedList.removeFirst(); |
|
Inserting X at Tail |
myLinkedList.addLast(X); |
|
Removing from Tail |
myLinkedList.removeLast(); |
|
Inserting Element X |
myLinkedList.add(X); |
|
Inserting Element X at index i |
myLinkedList.add(i, X); |
|
Removing Element X |
myLinkedList.remove(X); |
|
Removing Element at index i |
myLinkedList.remove(i); |
|
Getting Element at index i |
DataType value = myLinkedList.get(i) |
|
Setting Element at index i to X |
myLinkedList.set(i, X); |
|
Checking for Existence of element X |
boolean containsX = myLinkedList.contains(X); |
|
Size of LinkedList |
int size = myLinkedList.size(); |
|
Conversion to Array |
DataType[] array = myLinkedList.toArray(new DataType[0]); |
