Remember, here we will not talk about ArrayList vs LinkedList in Java which is another popular core Java interview question, Instead, here we will talk about array and linked list data structure from a coding/programming interview perspective.ītw, both are very similar because of is based upon array and is based upon the linked-list data structure. Though this discussion is valid from C/C++ and other programming language perspectives, I'll give you examples and explanations in Java. One of the traits of a good programmer is extensive knowledge of data structure and algorithm and that's why it's very important for you to learn the difference between array and linked list data structure and understand when to use an array over a linked list and vice-versa. Both array and linked list are two of the most popular and fundamental data structures in Computer Science and Programming, and Java supports both of them.

It's very simple and easy to answer but you just can't afford to miss this question in an interview. It is also a very popular question during practical exams in Computer Science degree courses like B.E. The difference between an array and a linked list is one of the frequently asked data structure and algorithm interview questions and you might have seen it before on your telephonic or face-to-face interview.
