What is the difference between List and Array in Java? Or the difference between Array and Vector!

stackoverflow.com/questions/7869212/… - arrays are primitives, List is an interface which defines a set of operations on sequential containers, and Vector implements List. Unless you meant ArrayList, and not Array. — wkl

In general (and in Java) an array is a data structure consisting of sequential memory storing a collection of objects.

List is an interface in Java, which means that it may have multiple implementations. One of these implementations is ArrayList, which is a class that implements the behavior of the List interface using arrays as the data structure.

There are a number of other classes that implement the List interface. One easy way to take a look at them is by viewing the Javadoc for List. On this page, you'll see "all known implementing classes," which are all of the kinds of lists in Java.
