序列化与反序列化

public class TestObject {

public static void main(String[] args) {
// TODO Auto-generated method stub
//对象的序列化--将对象以二进制的形式输出(没有确定输出到哪儿去)
// ArrayList<Student> al = new ArrayList<Student>();
// Student stu0 = new Student("HJ", 25,"四川","成都","九眼桥第三桥洞");
// Student stu1 = new Student("YP", 27,"四川","成都","九眼桥第2桥洞");
// al.add(stu0);
// al.add(stu1);
//
// ObjectOutputStream oos = null;
//
// try {
// oos = new ObjectOutputStream(new FileOutputStream("student.data"));
// oos.writeObject(al);
// } catch (FileNotFoundException e) {
// // TODO Auto-generated catch block
// e.printStackTrace();
// } catch (IOException e) {
// // TODO Auto-generated catch block
// e.printStackTrace();
// }finally{
// if(oos != null){
// try {
// oos.close();
// } catch (IOException e) {
// // TODO Auto-generated catch block
// e.printStackTrace();
// }
// }
// }


//反序列化--将输入的二进制流转换为对象(同样不确定二进制流的数据源)
ArrayList<Student> al = null;
ObjectInputStream ois = null;

try {
//使用了装饰器模式
ois = new ObjectInputStream(new FileInputStream("student.data"));
al = (ArrayList<Student>)ois.readObject();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally{
if(ois != null){
try {
ois.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

System.out.println(al.get(0));
System.out.println(al.get(1));
}

}
