如何将文本文件读入waitingRoom数组？我还需要能够使用此文件来添加和删除乘客吗？谁能帮忙x

package trainstation;

import java.util.Scanner;

public class TrainStation 
{

    static int WAITING_ROOM_CAPACITY = 30;

    private static Passenger[] waitingRoom = new Passenger[WAITING_ROOM_CAPACITY];
    private static PassengerQueue trainQueue = new PassengerQueue();


    public static void main(String[] args) 
    {

Answer 1

File myObj = new File("filename.txt");
Scanner myReader = new Scanner(myObj);

while (myReader.hasNextLine()) {

  String data = myReader.nextLine();  // The data of the txt file will depends on the format you wanted.
  System.out.println(data); // Or you can append data to an array ...

}

或者如果您的txt文件数据格式是这样的话

名称|姓氏| 1个名称1 |姓1 | 2

然后，您必须用分隔符将txt文件中的每一行数据分开。

File myObj = new File("filename.txt");
Scanner myReader = new Scanner(myObj);

while (myReader.hasNextLine()) {

  String[] data = (myReader.nextLine()).split(" | "); // It is already an array
  System.out.println(data); // Or you can append data to an array ...

}
