What is the difference between a vector and an Array? (Java)..

Answer / shiv

Array is not synchronized

Vector is synchronized class

By default array are type safe

To make a vector class type safe we need to implement
generics

Once Array size defined it will be fixed for the rest of

Vector can grow dynamically


Array pass no instance of test with Collection interface

Vector pass as it extends List which is a sub class of
Collection.
