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();
