关于ObjectInputStream的问题

Question

用什么样的方法能实现用ObjectInputStream中的readObject()循环的从文件中读取数据
请举例详细说明

Answer 1

Student stu1 = new Student(20,"zhangsan",25,"huaxue");
Student stu2 = new Student(18,"lisi",23,"wuli");
Student stu = null;
try
{
         FileOutputStream fos = new FileOutputStream("Student.txt");
ObjectOutputStream oos = new ObjectOutputStream(fos);
oos.writeObject(stu1);
oos.writeObject(stu2);
fos.close();
oos.close();
FileInputStream fis = new FileInputStream("Student.txt");
ObjectInputStream ois = new ObjectInputStream(fis);
while((stu = (Student)ois.readObject())!=null)
{
stu = (Student)ois.readObject();
System.out.println("Id: " + stu.getId());
System.out.println("Name: " + stu.getName());
System.out.println("Age: " + stu2.getAge());
System.out.println("Department: " + stu2.getDepartment());
fis.close();
ois.close();
}
}
catch(EOFException e)
{
e.printStackTrace();
}
程序运行的时候在while((stu = (Student)ois.readObject())!=null)出现错误
只能将第一第记录读出
Exception in thread "main" java.io.IOException: No such file or directory

Answer 2

System.out.println(  "Age:    "  +  stu.getAge());  
System.out.println(  "Department:    "  +  stu.getDepartment());
