public class Main {

    /**

    public static void main(String[] args) {
        try {
            URL my_url = new URL("http://www.vimalkumarpatel.blogspot.com/");
            BufferedReader br = new BufferedReader(new InputStreamReader(my_url.openStream()));
            String strTemp = "";
            while(null ! = (strTemp = br.readLine())){
                System.out.println(strTemp);
            }
        } catch (Exception ex){
            ex.printStackTrace();
        }
        // TODO code application logic here
    }

}

Thanks

So what's the error? Does it compile? If so, what happens when you run it, and what did you expect to happen?

The subject

Unable to display the UI

is a bit misguiding.

[Rob Spoor]

I agree. There is no UI involved here. Loh Peggie, please UseAMeaningfulSubjectLine. One that does explain the problem in a few words.

I wonder what the outout would look like , so I tried with a Java Ranch Site , but i am getting Connection timed out: connect

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
public class Main {
	public static void main(String[] args) {
		try {
			URL my_url = new URL("http://www.coderanch.com/forums");
			BufferedReader br = new BufferedReader(new InputStreamReader(
					my_url.openStream()));
			String strTemp = "";

			String line = br.readLine();

			while (line != null) {
				System.out.println(line);
			}

		} catch (Exception ex) {
			ex.printStackTrace();
		}
	}
}

Assuming a web browser works from the same machine, you must be behind a proxying firewall, either on our own machine, or somewhere on the network you're attached to. As we don't know anything about your setup, we can't tell you precisely what to do, but this page gives the general procedure once you know something about the proxy you need to get through.

Thanks for the information , atleast i will try at home .

Did you post real code? There was a compiler error in what you posted originally; when I corrected that, it worked nicely for me.
