为什么我的 while 循环不起作用？

Question

基本上它是一个使用其他 logreader 类的日志文件读取器函数，它的函数如 readLine() 和 hasMoreLines() 我不知道为什么我的 while 循环不能正常工作，因为它被假定输出我使用 tokenizer 创建的所有标记

public void readLogFile() throws Exception {

    LogReader lr = new LogReader();
    LogEntry [] arr = new LogEntry[700];
    String logLine;
    int count = 0;
    System.out.println("OUTSIDE WHILE LOOP"); // for testing

        logLine = lr.fileReader.nextLine(); // objct log reader
        System.out.println("A DAM LINE IN OUTER LOOP"); // for testing
        while (lr.hasMoreLines()) {
            StringTokenizer token = new StringTokenizer(lr.readLine());
            String date = token.nextToken();
            String time = token.nextToken();
            String siteName = token.nextToken();
            String computerName = token.nextToken();
            String sIpAddress = token.nextToken();
            String csMethod = token.nextToken();
            String csUriStem = token.nextToken();
            String csUriQuery = token.nextToken();
            String sPort = token.nextToken();
            String csUsername = token.nextToken();
            String csIpAddress = token.nextToken();
            String csVersion = token.nextToken();
            String csUserAgent = token.nextToken();
            String csCookie = token.nextToken();
            String csReferer = token.nextToken();
            String csHost = token.nextToken();
            String scStatus = token.nextToken();
            String scSubStatus = token.nextToken();
            String scWin32Status = token.nextToken();
            String scBytes = token.nextToken();
            String csBytes = token.nextToken();
            String timeTaken = token.nextToken();

//基本上它不执行下面的这部分

            LogEntry le = new LogEntry(date, time, siteName, computerName,
                    csMethod, sIpAddress, csUriStem, csUriQuery, sPort,
                    csUsername, csIpAddress, csVersion, csUserAgent,
                    csCookie, csReferer, csHost, scStatus, scSubStatus,
                    scWin32Status, scBytes, csBytes, timeTaken);
            arr[count++]=le;
            System.out.println(le.toString());
            System.out.println("A DAM LINE IN WHILE LOOP"); // for testing
        }

lr 刚刚初始化。 我没有看到任何赋值，这个控件没有进入 while 循环
