您可以使用一个boolean类型的变量来记录是否满足if条件，只要有一次满足就将这个变量置为true，当三次TUpdTm的值均不满足if条件时，判断这个变量是否为false，如果是则进入else。代码示例：

boolean isTUpdTmValid = false; // 记录TUpdTm是否满足if条件
while (calendar.getTime().before(TUpdEndTm)) {
    Date date = calendar.getTime();
    calendar.add(Calendar.DAY_OF_YEAR, 1);
    TUpdTm = sdf.format(date);
    String dir = rootdir + "/" + TUpdTm;

    ChannelSftp connect = FtpUtil.connect(username, password, host, port);
    List<String> rootFilelists = FtpUtil.listFiles(connect, rootdir);
    if (!rootFilelists.isEmpty() && rootFilelists.contains(TUpdTm)) {
        try {
