Java Examples - View the Last Modified Time of a Specified File on the Host
Java ExamplesThe following example demonstrates how to view the last modified time of a specified file on the host:
Main.java file
import java.net.URL;
import java.net.URLConnection;
import java.util.Date;
import java.text.SimpleDateFormat;
public class Main {
public static void main(String[] argv) throws Exception {
URL u = new URL("http://127.0.0.1/test/test.html");
URLConnection uc = u.openConnection();
SimpleDateFormat ft = new SimpleDateFormat ("yyyy-MM-dd hh:mm:ss");
uc.setUseCaches(false);
long timestamp = uc.getLastModified();
System.out.println("test.html file last modified time :" + ft.format(new Date(timestamp)));
}
}
The output of the above code execution is:
