对象的序列化,就是将Object转换成byte序列,反之叫对象的反序列化。
序列化流(ObjectOutInputStream),是过滤流 -------writeObject
反序列化流(ObjectInputStream)-----raedObject
序列化接口(Serializable)
对象必须实现序列化接口,才能进行序列化,否则出现异常
这个接口,没有任何方法,只是一个标准。
案例描述:Student,将它序列化到文件中,再反序列化读出。
Student类:
package Blog;
import java.io.Serializable;
public class Student implements Serializable{
private String stuno;
private String stuname;
private int stuage;
public Student(String stuno, String stuname, int stuage) {
super();
this.stuno = stuno;
this.stuname = stuname;
this.stuage = stuage;
}
public Student() {
super();
}
public String getStuno() {
return stuno;
}
@Override
public String toString() {
return "Student [stuno=" + stuno + ", stuname=" + stuname + ", stuage=" + stuage + "]";
}
public void setStuno(String stuno) {
this.stuno = stuno;
}
public String getStuname() {
return stuname;
}
public void setStuname(String stuname) {
this.stuname = stuname;
}
public int getStuage() {
return stuage;
}
public void setStuage(int stuage) {
this.stuage = stuage;
}
}
序列化Student到obj.dat中
package Blog;
import java.io.FileOutputStream;
import java.io.ObjectOutputStream;
public class ObjectSeriaDemo1 {
public static void main(String[] args) throws Exception{
String file = "obj.dat";
ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(file));
Student stu = new Student("1001","zhangsan",20);
oos.writeObject(stu);
oos.flush();
oos.close();
}
}
反序列化obj.dat
package Blog;
import java.io.FileInputStream;
import java.io.ObjectInputStream;
public class ObjectSeriaDemo1 {
public static void main(String[] args) throws Exception{
String file = "obj.dat";
ObjectInputStream ois = new ObjectInputStream(new FileInputStream(file));
Student stu = (Student)ois.readObject();
System.out.println(stu);
ois.close();
}
}
