使用对象流来完成序列化和反序列化操作：
ObjectOutputStream：通过writeObject()方法做序列化操作的
ObjectInputStream：通过readObject方法来做反序列化操作的
做序列化操作必须存在对象的字节码对象。
1 public class ObjectStreamDemo { 2 public static void main(String[] args) throws Exception { 3 4 File file = new File("obj.txt"); 5 //writeObject(file); 6 readObject(file); 7 } 8 9 private static void readObject(File file) throws Exception { 10 ObjectInputStream in = new ObjectInputStream(new FileInputStream(file)); 11 User user = (User) in.readObject(); 12 System.out.println(user.getName()); 13 in.close(); 14 } 15 16 private static void writeObject(File file) throws Exception { 17 ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream(file)); 18 out.writeObject(new User("wxd","123",21)); 19 out.close(); 20 } 21 }
