java 怎样将importData的值加入容器中

package hotel1;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;

import hotel.CloseStreamMethod;

public class ImportData{
public ArrayList roomsLists = new ArrayList();

public static void main(String[] args) {
ImportData ip = new ImportData();
ip.importRooms();
}

public String importData(){

File src = new File("/Users/handsomeboy/eclipse-workspace/Coursework/src/hotel1/rooms.txt");

BufferedReader br = null;

String lines = null;
try {
br = new BufferedReader(new FileReader(src));
String line = null;
while((line = br.readLine()) != null) {
lines += line;
}

} catch (IOException e) {
e.printStackTrace();
} finally {
CloseStreamMethod csm = new CloseStreamMethod();
csm.close(br);
}
return lines;
}
public void importRooms() {

String[] content = importData().split("\n");
for (String row : content) {
if(row != null) {
String[] contents = row.split(",");
if (contents.length == 5) {
roomsLists.add(new Rooms(Integer.parseInt(contents[0]),
RoomType.valueOf(contents[1].toUpperCase()),
Double.parseDouble(contents[2]),
Integer.parseInt(contents[3]),contents[4]));
}
}
}
System.out.println(roomsLists);
}
}

输出内容:
[]

文本内容：
101,double,80.00,2,own bathroom
102,double,80.00,2,own bathroom
103,twin,70.00,2,shared bathroom
104,twin,70.00,2,shared bathroom
201,double,80.00,2,own bathroom
202,single,70.00,1,own bathroom
301,family,90.00,4,own bathroom

    this.facilities = facilities;
}
 public String toString(){
        return "\n" + "  RoomNumber:" + roomNumber + "  Type:" + roomType + "  Price:" + price +

}

}

终于改好了
