序列化就是做持久化存储数据。将整个对象信息进行存储在硬盘上。
代码
1、创建Student类
public class Student implements Serializable
{
private int age
;
private String name
;
public int getAge
() {
return age
;
}
public void setAge
(int age
) {
this.age
= age
;
}
public String getName
() {
return name
;
}
public void setName
(String name
) {
this.name
= name
;
}
}
2、StudentTestMain
public class StudentTestMain
{
public static void main
(String
[] args
) throws Exception
{
//将对象存入桌面
// Student student
= new Student
();
// student.setAge
(20
);
// student.setName
("wu");
// ObjectOutputStream out
= new ObjectOutputStream
(new FileOutputStream
("C:\\Users\\HP\\Desktop\\student.txt"));
// out.writeObject
(student
);
// out.close
();
//
//将存入桌面的对象调入内存当中
Student student
;
ObjectInputStream
in = new ObjectInputStream
(new FileInputStream
("C:\\\\Users\\\\HP\\\\Desktop\\\\student.txt"));
student
= (Student
) in.readObject
();
System.out.println
(student.getAge
() +
" "+ student.getName
());
}
}
