序列化与反序列化

• 对象序列化为字节流&从字节流还原对象

• 一个实现了相应接口的类

public class Employee implements Serializable {
    private static final long serialVersionUID = 1L;
    private transient Address address;
    private Person person;
    // setters and getters
    private void writeObject(ObjectOutputStream oos)  throws IOException {
        oos.defaultWriteObject();
        oos.writeObject(address.getHouseNumber());
    }

    private void readObject(ObjectInputStream ois) throws ClassNotFoundException, IOException {
        ois.defaultReadObject();
        Integer houseNumber = (Integer) ois.readObject();
        Address a = new Address();
        a.setHouseNumber(houseNumber);
        this.setAddress(a);
    }
}
public class Address { private int houseNumber; }
