當我打開URL時，我有很多文件，有時會添加新文件。我想想要讀取URL中新增文件的內容。 目前我能夠在給定文件名時讀取文件內容。沒有提供任何文件名，我無法讀取最新的文件。如何獲取最新的文件和讀取內容有任何建議..使用java知道URL中最新上傳的文件名
規則所列的URL的文件名時，從文件中讀取內容：
URL url = new URL("https://xyz.abc.com/filesPath/myFile.pptx");
HttpsURLConnection connection = ((HttpsURLConnection) url.openConnection());
InputStream input;
input = connection.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(input));
String msg = null;
while ((msg = reader.readLine()) != null) {
System.out.println(msg);
}
在上面的代碼中，給出的網址具有打開文件並讀取內容的文件路徑。我如何從可用文件列表（https://xyz.abc.com/filesPath/）中讀取最新文件的內容。
url路徑https://xyz.abc.com/filesPath/上傳了多個文件。
--EDITED--
下面是HTML響應當與How to get list of files/directories of an directory url in java?

文件名提及的推薦代碼 嘗試是spreadTestReport.xls在上述響應。
你可以訪問文件的列表？如果服務器不提供目錄列表，則可能無法完成。 – Compass
@ Compass-是我可以訪問文件列表。我可以點擊任何文件並打開它。一旦文件被打開，如果我在我的代碼中給出了整個路徑，我也可以閱讀這些內容。 – sss
