Because each element stored as a separate node and there can be multiple nodes with the same data. A class, in simple terms, is a blueprint or template for an object. 2) Array  and ArrayList stores in contiguous memory locations to store their values. Many times, we can’t predict the number of elements in advance.But ArrayList has dynamic size that can increase or decrease during manipulation. As we know Array and ArrayList are two other popular data structure. i). LinkedList is fast in manipulation because no shifting needs to occur.
