Java 序列化与反序列化练习
import java.io.*;
//电影类型
enum MovieType implements Serializable{
Comedy("喜剧片"),
Action("动作片"),
Romatic("爱情片"),
ScienceFiction("科幻片");
private final String name;
MovieType(String name){
this.name = name;
}
public String get(){
return name;
}
}
//电影
class Movie implements Serializable{
String name;
MovieType type;
String where;
Movie(String where,String name,MovieType a){

}
void printinfo(){
System.out.print(this.name+"\n"+"类型："+this.type.get()+"\n"+"放映厅："+this.where+"\n");
}
}
//电影放映时间段
class MovieSchedule implements Serializable{

String date;
MovieSchedule(String date,String time){
this.time = time;
this.date = date;
}
void printinfo(){

}
}
//座位
class Seat implements Serializable{

}
void printinfo(){

}
//电影票

}
public class MovieSet {
public static void main (String[] args) {

os.writeObject(one);
os.close();
}catch(Exception ex){
ex.printStackTrace();

}
}
利用Date类型做成的反序列化功能，Date和SimpleDateFormat
