我implement该怎么Serializable接口？

我有class Student,并且需要能够将其保存到磁盘.对于我的作业,我必须序列化五个不同的Student对象并将它们保存到文件中.

class Student {
     String mFirstName;
     String mSecondName;
     String mPhoneNumber;
     String mAddress;
     String mCity;

Student(final String pFirstName, final String pSecondName, final String pPhoneNumber, final String pAddress, final String pCity){
    this.mFirstName = pFirstName;
    this.mSecondName = pSecondName;
    this.mPhoneNumber = pPhoneNumber;
    this.mAddress = pAddress;
    this.mCity = pCity;

}}

我已经尝试使用ObjectOutputStream序列化a Student,但它会抛出一个错误:

ObjectOutputStream lOutputStream = new ObjectOutputStream(new FileOutputStream("file.txt", true));
lOutputStream.write(new Student("foo","bar","555-1234","Flat 40","Liverpool"));
