Dynamic Data Structures Overview
... Vectors can be thought of as arrays that can grow in length as needed during run time. The base type of all vectors is Object. Thus, vector elements can be of any class type, but not primitive types. A linked list is a data structure consisting of objects known as nodes, such that each node can cont ...
