Java下对象的序列化和反序列化（写出和读入）

代码如下：

public class MyWork {public static void main(String[] args) throws IOException, ClassNotFoundException {//序列化File f = new File("testFile/testObject.txt");ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(f));ArrayList<Student> list1 = new ArrayList<>();Student s1 = new Student("张三",18);Student s2 = new Student("李四",19);Student s3 = new Student("王武",20);list1.add(s1);list1.add(s2);list1.add(s3);oos.writeObject(list1);oos.close();//反序列化ObjectInputStream ois = new ObjectInputStream(new FileInputStream(f));ArrayList<Student> list2 = (ArrayList<Student>) ois.readObject();Iterator<Student> it = list2.iterator();while(it.hasNext()){Student stu = it.next();System.out.println(stu.getName() + "======" + stu.getAge());}ois.close();}
}
