Java 读整行而不是最长的单词

我正在编写一个程序，该程序读取文本文件并打印行数、最长行数、每行上的令牌数以及每行上最长令牌的长度

我在阅读最长单词时遇到问题，我的程序给我的是每行的字母数，而不是最长单词的字母数

文本文件内容： 预期产出： 实际产量： 代码： 如果“代币”不是一封信，这将为您提供：

public static void main(final String... args)
    throws IOException
{
    String fileName;

    System.out.printf("Please enter the name of a file\n");

    try (
        final Scanner scanner = new Scanner(System.in);
    ) {
        fileName = scanner.nextLine();
    }

    // If we reached this point, good; .nextLine() only fails with unchecked
    // exceptions, so if it failed we won't be here. And the scanner will be closed.

    final Path path = Paths.get(fileName);
    int lineCount = 0;

    for (final String line: Files.readAllLines(path, StandardCharsets.UTF_8)) {
        lineCount++;
        analyzeLine(line);
    }
    System.out.printf("TOTAL: %d lines\n", lineCount);
}

private static void analyzeLine(final String line)
{
    final String[] tokens = line.split("\\W+");
    int largestToken = 0;
    for (final String token: tokens)
        if (token.length() > largestToken)
            largestToken = token.length();

    System.out.printf("This line: %d tokens, largest token has length %d\n",
        token.length, largestToken);
}
