java - 文件扫描仪扫描仪未正确扫描所有信息

Question

我有一个文件扫描器类，即用于从客户列表中读取名称(我还有另一个文件，即用于读取 Customer 对象，但这些文件正在被读得好)。我的列表如下所示(我只是跳过数字，然后将名称读入字符串name):

1、鲍比

2，乔

3、苏

4，玛丽

5、维克多

但由于某种原因，当我使用 toString() 打印时，显示的唯一名称是 Victor。我希望每个 customer 对象都有其自己的名称各自的名字。

问题:如何让 lineScanner 正确读取所有五个名称，然后将它们显示在 toString() 中？

//reads in customer name info
File customerList = new File("./src/Customers.txt");
Scanner fileScanner = new Scanner(customerList);

//while there is a new line, goes to next one
while(fileScanner.hasNextLine())
{
    String line = fileScanner.nextLine();
    Scanner lineScanner = new Scanner(line);
    lineScanner.useDelimiter(",");

    //while there is a new attribute to read in on a given line, reads data
    while(lineScanner.hasNext())
    {
        lineScanner.next();
        name = lineScanner.next();
        customer1 = new Customer(ranking, name, tvTimeTotal1, exerciseTimeTotal1);
        customer2 = new Customer(ranking, name, tvTimeTotal2, exerciseTimeTotal2);
        customer3 = new Customer(ranking, name, tvTimeTotal3, exerciseTimeTotal3);
        customer4 = new Customer(ranking, name, tvTimeTotal4, exerciseTimeTotal4);
        customer5 = new Customer(ranking, name, tvTimeTotal5, exerciseTimeTotal5);
    }
}


System.out.println(customer1.toString());
System.out.println(customer2.toString());
System.out.println(customer3.toString());
System.out.println(customer4.toString());
System.out.println(customer5.toString());

类似这样的吗？

File customerList = new File("./src/Customers.txt");
Scanner fileScanner = new Scanner(customerList);

List<String> customerNames = new ArrayList<String>();
while(fileScanner.hasNextLine())
{
    String line = fileScanner.nextLine();
    Scanner lineScanner = new Scanner(line);
    lineScanner.useDelimiter(",");
    lineScanner.next(); // Discard number
    customerNames.add(lineScanner.next());
}

for(String name : customerNames)
{
    System.out.println(name);
}
