我需要为学校项目创建自己的注册表。
我想拥有
1
room, room
2
room, room
hall, hall
3
room, room
hall, hall
dorm, dorm
但我得到的只是
1
room,room
2
room,hall
hall,hall
3
room,dorm
hall,dorm
dorm,dorm
所以不知何故，设施参考在某处发生了变化，但我不知道如何解决这个问题。任何人都可以帮忙吗？
这些是我的代码。
public class registry {
static List<registryRecord> register = new ArrayList<registryRecord>();
public static boolean bind(String name, facility ref){
for(registryRecord r:register){
if(r.name.equals(name)) //check if the name is already binded
return false;
}
registryRecord newRecord = new registryRecord(name, ref);
register.add(newRecord);
for (registryRecord r:register){
System.out.println(r.name +","+ r.ref.name);
}
return true;
}
public class registryRecord {
String name;
facility ref;
public registryRecord(String name, facility ref){
this.name = name;
this.ref = ref;
}
public class server {
public static void main(String args[]) throws Exception{
facility room = new facility("room");
System.out.println(1);
boolean test = registry.bind("room", room);
facility hall = new facility("hall");
System.out.println(2);
boolean test2 = registry.bind("hall", hall);
facility dorm = new facility("dorm");
System.out.println(3);
registry.bind("dorm", dorm);
}
public class facility {
public static String name;
static List<booking> bookings;
public facility(String name){
this.name=name;
this.bookings = new ArrayList<booking>();
}
}
