Java提供了一种称为对象序列化的机制,该机制可以将对象表示为字节序列,其中包括对象的数据以及有关对象的类型和存储在对象中的数据类型的信息。
import java.io.*; public class SerializeDemo { public static void main(String [] args) { Employee e = new Employee(); e.name = "Reyan Ali"; e.address = "Phokka Kuan, Ambehta Peer"; e.SSN = 11122333; e.number = 101; try { FileOutputStream fileOut = new FileOutputStream("/tmp/employee.ser"); ObjectOutputStream out = new ObjectOutputStream(fileOut); out.writeObject(e); out.close(); fileOut.close(); System.out.printf("Serialized data is saved in /tmp/employee.ser"); } catch (IOException i) { i.printStackTrace(); } } }
