IO流(对象的序列化)

public class ObjectStreamDemo {

public static void main(String[] args) throws FileNotFoundException, IOException, ClassNotFoundException {

// TODO Auto-generated method stub

// writeObj();

注意 ：静态变量或者加修饰（transient） 是不能被序列化的  静态在方法区  只能把堆里面的序列化

readObj();

}

public static void writeObj() throws FileNotFoundException, IOException {

ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream("/Users/denmeiho/Desktop/obj.txt"));

oos.writeObject(new Person("lisi", 39));

oos.close();

}

public static void readObj() throws FileNotFoundException, IOException, ClassNotFoundException{

ObjectInputStream ois = new ObjectInputStream(new FileInputStream("/Users/denmeiho/Desktop/obj.txt"));

Person p = (Person) ois.readObject();

System.out.println(p);

ois.close();

}
