使用BufferedReader从文本文件中读取String和int到HashSet Java中

Question

The text file look like this:

name1

1

name2

2

The method prints:

[name: name1 shirt number: 1]

This is how I want it to print:

[name: name1 shirt number: 1, name: name2 shirt number: 2, and so on]

It only prints the first element. Feels like I tried everything but I can't get it to work. Someone got a possible solution?

public void loadPlayerDatabase(String fileName) throws IOException {

    try (BufferedReader reader = new BufferedReader(new FileReader(fileName))) {

        String currentLine;
        int counter = 0;
        String name = null;

        while ((currentLine = reader.readLine()) != null) {
            int number = Integer.parseInt(reader.readLine());
            if (counter % 2 == 0) {
                name = currentLine;
                counter++;

            } else {
                Player player = new Player();
                player.setName(name);
                players.add(player);
                player.setNumber(number);
                counter++;
            }
        }
        counter++;
    } catch (NumberFormatException n) {
        System.out.println("That didn't work!" + n.getMessage());
    }
    System.out.println(players);
}

Answer 1

This should work.

The readLine() function continues on to the next line in the input and hence you don't need to skip lines.
