Advanced API (serialization & deserialization)

serialize  ObjectOutputStream
                      Save the objects generated in memory to a text file

                         All classes to be serialized must implement Serializable Interface

 Student implements Serializable{

      private static final long serialVersionUID = 1L;

}

Deserialization ObjectInputStream
                      The contents of the local file （ object ）-- Read to memory

The basic format ：

serialize
         Prepare an object
        Student stu = new Student(1, " Huqing stick ");
        File file = new File("D:\\stu.bak");
        FileOutputStream fos = new FileOutputStream(file);
         Write through serialized stream ObjectOutputStream
        ObjectOutputStream oos = new ObjectOutputStream(fos);
         Write an object through the serialization stream
        oos.writeObject(stu);
         close
        oos.close(); 

        fos.close();
