java通过序列化实现对象的深度克隆

1、建立一个java工程，其基本目录见下图，小编采用的是eclipse软件。

2、编写一个子类，该子类被我们要克隆的类引用，用以显示该深度克隆的意义。class Address implements Serializable{ private String state; private String privance; private String city; public Address(String state,String privance ,String city){ this.state=state; this.privance=privance; this.city=city; } public String getCity(){ return this.city; } public String getState(){ return this.state; } public String getPrivance(){ return this.privance; } public void setState(String state){ this.state=state; } public void setPrivance(String privance){ this.privance=privance; } public void setCity(String city){ this.city=city; } public String toString(){ StringBuilder sb=new StringBuilder(); sb.append("国窖："+state+","); sb.append("省："+privance+","); sb.append("市："+city+","); return sb.toString(); } }

3、编写要被克隆的类，该类就是我们要实现克隆的具体。

4、编写我们的实验代码，该代码用于实现我们的一个克隆实例，具体如下图所示，代码如下： public static void main(String[] args) { System.out.println("序列化之前"); Address address=new Address("中国","吉林","长春"); Employees employee1=new Employees("小明", 30, address); System.out.println("员工1的信息："); System.out.println(employee1); System.out.println("序列化之后："); ObjectOutputStream out=null; ObjectInputStream in=null; Employees employee2=null; try{ out=new ObjectOutputStream(new FileOutputStream("employees.dat")); out.writeObject(employee1); in=new ObjectInputStream(new FileInputStream("employees.dat")); employee2=(Employees)in.readObject(); }catch(FileNotFoundException e){ e.printStackTrace(); }catch(IOException e){ e.printStackTrace(); }catch(ClassNotFoundException e){ e.printStackTrace(); }finally{ } employee2.getAddress().setState("中国"); employee2.getAddress().setPrivance("四川"); employee2.getAddress().setCity("成都"); employee2.setName("大明"); employee2.setAge(24); System.out.println("员工1的信息："); System.out.println(employee1); System.out.println("员工2的信息:"); System.out.println(employee2); }

5、查看效果，单击“编译运行”运行按钮，我们可以看到此深度克隆的实现效果，往细细思考。
