Java Vector Class

The vector class implements a dynamic array. and ArrayList and similar, but the two are different: The vector is accessed synchronously. Vectors contain a number of traditional methods that do not belong to the set framework.

Use of the Vector class

First, the vector class in Java can implement an automatically growing array of objects, in contrast to the use of ArrayList class is faster than the vector class, wherein the ArrayList is not synchronous;Second, if the design involves
