12.ObjectInputStream/ObjectOutputStream对象操作流

可以进行序列化/反序列化，将一个对象写出，或者将一个序列化的对象读入。

12.1 ObjectInputStream 对象操作输入流/反序列化

ObjectInputStream构造方法

public ObjectInputStream(InputStream in)

ObjectInputStream重要方法

public final Object readObject()

ObjectInputStream使用

public class Person implements Serializable {

private String name;

private String age;

public Person(String name, String age) {

this.name = name;

this.age = age;

}

...

}

File dir = Environment.getExternalStorageDirectory();

File dst = new File(dir, "dst4.txt");

FileInputStream fis = new FileInputStream(dst);

ObjectInputStream ois = new ObjectInputStream(fis);

Person person = (Person) ois.readObject();//Person一定要实现Serializable接口才可序列化

Log.d("xl", person.toString());

ois.close();

12.2 ObjectOutputStream 对象操作输出流/序列化

ObjectOutputStream构造方法

public ObjectOutputStream(OutputStream out)

ObjectOutputStream重要方法

public final void writeObject(Object obj)

ObjectOutputStream使用

public class Person implements Serializable {

private String name;

private String age;

public Person(String name, String age) {

this.name = name;

this.age = age;

}

...

}

File dir = Environment.getExternalStorageDirectory();

File dst = new File(dir, "dst4.txt");

FileOutputStream fos = new FileOutputStream(dst);

ObjectOutputStream oos = new ObjectOutputStream(fos);

Person p = new Person("a", "1"); //Person一定要实现Serializable接口才可序列化

oos.writeObject(p);

oos.close();
