The Collection in Java is a framework that provides a facility to store and manipulate the group of objects.

Java Collections can achieve all the operations that you perform on a data such as searching, sorting, insertion, manipulation, and deletion.

ArrayList
Arraylist class implements List interface and it is based on an Array data structure. It is widely used because of the functionality and flexibility it offers.
ArrayList is a resizable-array.
It implements all optional list operations, and permits all elements, including null.
Vector
Very similar to ArrayList in functionality but it is synchronized and thread safe.
LinkedList
The elements are linked using pointers and addresses. Each element is known as a node.
Due to the dynamicity and ease of insertions and deletions, they are preferred over the arrays.
It also has few disadvantages like the nodes cannot be accessed directly instead we need to start from the head and follow through the link to reach to a node we wish to access.
