尝试将我的数据存储在数组内的文本文件中

Question

正在尝试 Java 不太确定如何将文本文件中的信息存储到数组中，我的票证对象数组有一个名称，即地址，然后是编号，而不是数组

public static void readTicket(ArrayList<Ticket>tickets) throws IOException
    {
        String name;
        String address;
        int phone;
        int [] numbers;
        //1 create file
        File file1 = new File("ticketdata.txt");        
        //2 create a file writer class
        FileWriter fw = new FileWriter(file1);
        //3 create a print writer class
  //pass participants through

        Scanner scan = new Scanner(file1);

        while(scan.hasNextLine())
        {
            name = scan.next();
            address = scan.next();
            phone = scan.nextInt();
            numbers = scan.next(); //error
            tickets.add(new Ticket(name, address, phone, numbers));
            System.out.println(scan.nextLine());
        }
    }

我知道我所做的可能是完全错误的。这也是我 ticketdata.txt

中的内容

Answer 1

您可以使用 forEachRemaining 读取剩余数字，然后使用 toArray()

转换为数组

 while(scan.hasNextLine())
{
    List<Integer> numbersList = new ArrayList<>();
    name = scan.next();
    address = scan.next();
    phone = scan.nextInt();
    numbers = scan.forEachRemaining(e->numbersList.add(Integer.valueOf(e))); 
    tickets.add(new Ticket(name, address, phone, numbersList.toArray()));
    System.out.println(scan.nextLine());
}
