ArrayList vs LinkedList in Java

• An array is a collection of items stored in contiguous memory locations
• ArrayList and LinkedList are classes implemented to solve the limitation of the array's fixed size
• ArrayList is part of the collection framework and provides dynamic arrays in Java
• LinkedList is a linear data structure where elements are linked using pointers and addresses
• ArrayList has fast indexed access time but can be slow when inserting or deleting elements from the middle
• LinkedList does not use an array to store its elements and is preferred for dynamicity and ease of insertions and deletions
• Each element in a LinkedList is represented by a node that contains a reference to the data stored in the node and a reference to the next node in the list
• Retrieving elements from an ArrayList by an index is very quick
• Inserting or deleting elements from the middle of an ArrayList can be slow as the entire array needs to be shifted in memory
• Each element in a LinkedList is a separate object with a data part and an address part
