DataInputStream twice on the same InputSrteam

Question

The code below throws en exception:
import java.io.DataInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.URL;
public class TwiceDataInputStream {
     public static void main(String[] args) throws IOException {
          URL u1 = new URL("http://www.yahoo.com");
          InputStream is1 = u1.openStream();
          DataInputStream dis = new DataInputStream(is1);
          System.out.println(dis.readInt());
          dis.close();
          //NOT AN OPTION!
          //is1 = u1.openStream();
          dis = new DataInputStream(is1);
          //Exception here
          System.out.println(dis.readInt());
          dis.close();
          is1.close();
}My question is: what should I do to be able to use is1 again?

Answer 1

However, if you're trying to read from the same stream twice, you can't do it. You could use a PushbackInputStream, I guess, but that would kind of suck. A better approach would be to read once and then provide the bytes to the two different processing entities.
