* Exercise: sequence sets with 
* Step : 
* 1, define a storage Person object ArrayList set 
* 2, to a collection stored in the person object 
* 3, to create a serialized stream ObjectOutputStream, the collection serializing 
* 4, a method using an ObjectOutputStream object the writeObject, for collection serialization 
* 5, creating a deserialized ObjectInputStream stream 
*. 6, a method using ObjectInputStream object readObject read the saved file collection 
* 7, converted into a set of type Object type ArrayList 
* 8, binding to traverse ArrayList 
* 9, free up resources
