If I understand you correctly, I think this blog post will answer your question, with code showing example of using InputStream:

You can get last modified date with lastModified().

File file = new File(<file path>);
long lastModified = file.lastModified();

But lastModified() returns unix time. You can convert it with format.

Date date = new Date(lastModified);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss:SS");
String formattedDate = sdf.format(date);

Take a look at the documentation of File class, there are lots of methods to get any kind of information about a file.
