public class Student implements Serializable {
private String name;
private char sex;
private int year;
private double gpa;
public Student() {
}
public Student(String name,char sex,int year,double gpa) {
this.name = name;
this.sex = sex;
this.year = year;
this.gpa = gpa;
}
public void setName(String name) {
this.name = name;
}
public void setSex(char sex) {
this.sex = sex;
}
public void setYear(int year) {
this.year = year;
}
public void setGpa(double gpa) {
this.gpa = gpa;
}
public String getName() {
return this.name;
}
public char getSex() {

把Student类的对象序列化到文件/Users/sschen/Documents/student.txt，并从该文件中反序列化，向console显示后果。期货代码如下：
public class UserStudent {
public static void main(String[] args) {
Student st = new Student("Tom",'M',20,3.6);
File file = new File("/Users/sschen/Documents/student.txt");
try {
file.createNewFile();
}
catch(IOException e) {
e.printStackTrace();
}
try {
//Student对象序列化过程
FileOutputStream fos = new Fi<em style="color:transparent">来源[email protected]搞@^&代*@码网</em>leOutputStream(file);
ObjectOutputStream oos = new ObjectOutputStream(fos);
oos.writeObject(st);
oos.flush();
oos.close();
fos.close();
//Student对象反序列化过程
FileInputStream fis = new FileInputStream(file);
ObjectInputStream ois = new ObjectInputStream(fis);
Student st1 = (Student) ois.readObject();
System.out.println("name = " + st1.getName());
System.out.println("sex = " + st1.getSex());
System.out.println("year = " + st1.getYear());
System.out.println("gpa = " + st1.getGpa());
ois.close();
fis.close();
}
catch(ClassNotFoundException e) {
e.printStackTrace();
}
catch (IOException e) {
e.printStackTrace();
}
}
}
而查看文件/Users/sschen/Documents/student.txt，其内保留的内容并不是能够容易浏览的内容：
