How to know current speed of connection in Kbps?

Question

Does anyone know how to know the speed of network/internet connection? I couldn't find any member method of JAVA's class that returns this value. Very appreciate for all your hints.

Answer 1

Try something like this:public class Test
  public static void main(String[] argv)
    try
      URL url = new URL("http://java.sun.com"); /* put a pointer to some big image here */
      InputStream is = url.openConnection().getInputStream();
      int bytes = 0;
      long ms = System.currentTimeMillis();
      while(is.read() != -1) bytes++;
      ms = System.currentTimeMillis() - ms;
      double kbps = ((double)bytes / ((double)ms / 1000)) / 1024;
      System.out.println("kbps = " + (long)kbps);
      System.exit(0);
    catch(Throwable t)
      t.printStackTrace();
      System.exit(-1);
}I suggest you repeat this test for several pointers and take the average...
