  4. 4. LinkedList A linked list is a linear data structure which is constituted by a chain of nodes in which each node contains a value and a pointer to the next node in the chain.

  10. 10. Similarities between LinkedList & ArrayList They are the implementations of the List interface. They maintain the insertion order of the elements. Their classes are non-synchronized. Iterator & ListIterator returned by these classes are fail-fast www.edureka.co/java-j2ee-soa-training

  13. 13. ARRAYLIST Python LINKEDLIST Insertion, deletion and removal operations are faster in LinkedList because no need for resize as it is in ArrayList. Operation Insertion, addition, and removal operations are quite faster Comparatively the operations are slow here LinkedList ArrayList www.edureka.co/java-j2ee-soa-training
  14. 14. ARRAYLIST Python LINKEDLIST LinkedList is based on doubly linked list implementation whereas ArrayList is based on the concept of a dynamically resizable array, Implementation Follows Doubly linked list implementation Follows the concept of dynamically resizable array LinkedList ArrayList www.edureka.co/java-j2ee-soa-training
  15. 15. ARRAYLIST Python LINKEDLIST A LinkedList class can be used as a list and a queue because it implements List and Deque interfaces whereas ArrayList can only implement Lists. Process A LinkedList class can be a list and a queue because it implements List and Deque interfaces An ArrayList class can be a list because it implements only Lists LinkedList ArrayList www.edureka.co/java-j2ee-soa-training
  16. 16. ARRAYLIST Python LINKEDLIST A LinkedList consumes more memory than an ArrayList because every node in a LinkedListstores two references, whereas ArrayList holds only data and its index Memory Memory consumption in LinkedList is high Less compared to LinkedList LinkedList ArrayList www.edureka.co/java-j2ee-soa-training
