将对象写入文件，在以读出对象:
//两个student对象
Student stu1=new Student(19,"zhangsan",25,"Chemist");
Student stu2=new Student(20,"lis",30,"Physics");
//将stu1和stu2写入student.txt文件中
FileOutputStream fos=new FileOutputStream("student.txt");
ObjectOutputStream os=new ObjectOutputStream(fos);
os.writeObject(stu1);
os.writeObject(stu2);
os.close();
//从student.txt文件中读出stu3和stu4
Student stu3 = null;
Student stu4 = null;
FileInputStream fis=new FileInputStream("student.txt");
ObjectInputStream is=new ObjectInputStream(fis);
stu3=(Student)is.readObject();
stu4=(Student)is.readObject();
is.close();
