Linked List

The remove methods of the Linked List class are used to remove an element from the linked list. This post will discuss the remove methods in the Linked List class of java. We have three overloaded remove method implementations in the Linked List class – public E remove() public E remove(int index) public boolean remove(Object […]

In this post, we will discuss the peek(), peekFirst(), and peekLast() methods of the Java LinkedList class. These methods retrieve the element present at the start or the end of the linked list. public E peek() peek() method is introduced in Java 5. What does it do? It retrieves the linked list’s first node (

In this post, we will discuss the offer, offerFirst, and offerLast methods of the Java LinkedList class. The offer methods add elements at the linked list’s start or end. public boolean offer(E e) What does it do? It will take an element or object as an argument and add it at the end of the

isEmpty() is used to check whether the linked list is empty or not. In this post, we will discuss the isEmpty() method of the Java Linked List class in detail. Method declaration – public boolean isEmpty() What does it do? It will tell you whether the linked list is empty or not by checking the

In this post, we are going to discuss the get(), getFirst() and getLast() method of the LinkedList class. A linked list doesn’t allow random access to the elements, but it provides us with certain methods to access the elements of a list. Below are some of these methods public E get(int index) public E getFirst()

The descendingIterator() method has been present since Java 1.6 and is used to iterate the linked list in the reverse order. In this post, we will discuss the descendingIterator() method of the Linked List class. Method declaration – public Iterator descendingIterator() What does it do? It helps in iterating the linked list in reverse order.

contains() method checks whether the specified element is present in the list or not, and the containsAll() method checks whether all elements of the specified collection are present in the list. This post will discuss contains and containsAll methods implemented in the Linked List class. public boolean contains(Object o) What does it do? It will

The clear() method removes the elements present in the linked list. In this post, we will discuss the clear() method of the Linked List class in detail. Method declaration – public void clear() What does it do? It will remove all the elements present in the linked list, and the linked list will be empty.

addFirst method adds the elements at the beginning of the list, whereas the addLast method adds the elements at the end. In this post, we will learn about both methods in detail. public void addFirst(E e) What does it do? As the name suggests, it will insert the element at the beginning of the linked

In this post, we will be looking at the addAll() method of the Linked List class in Java. addAll() method is used to add the elements of a Collection into the linked list. There are two overloaded implementations of the addAll methods, which are listed below – public boolean addAll(Collection c) public boolean addAll(int index,
