Java Learning Notes-serialization and deserialization

The first way to persist data. It is also possible to break the data out of line-by-row in a file before serialization, and then read it on a line-by-row basis.

such as the Student class

Use the character output stream to store all the properties of the student class in a local file:

Zhang San |18| male

John Doe |18| Women

Read a row, separate data for the student's Name,age,gender, create student objects and join the student collection

Loop up one step until Br.readline = null

It is unclear how this method stores other information about the object.

Here's a list of serialization

On the code:

1  Public classSerializabledemo {2 3      Public Static voidMain (string[] args) throws IOException, ClassNotFoundException {4         //serializes the object obj, saving obj to the local file Obj.bin. Class for object obj must serializable interface5OutputStream OS =NewFileOutputStream ("/home/yanshaochen/public/obj.bin");//OutputStream Abstract class6ObjectOutputStream Oos =NewObjectOutputStream (OS);//ObjectOutputStream Instance Class7Oos.writeobject (obj);//Persistence of obj8 oos.close ();9         //deserializationTenInputStream is=NewFileInputStream ("/home/yanshaochen/public/obj.bin"); OneObjectInputStream Ois =NewObjectInputStream ( is); A@SuppressWarnings ("unchecked") -Object obj = (object) ois.readobject ();//classnotfoundexception exceptions may occur for casts -     } the}
