This is the working HTTP GET requestcode in java when all keys are in hand. Hope it does your work.

import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;
import oauth.signpost.OAuthConsumer;
import oauth.signpost.commonshttp.CommonsHttpOAuthConsumer;
import oauth.signpost.exception.OAuthCommunicationException;
import oauth.signpost.exception.OAuthExpectationFailedException;
import oauth.signpost.exception.OAuthMessageSignerException;
import org.apache.http.*;
import org.apache.http.client.*;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.client.methods.*;  //HttpHead, HttpPut, HttpGet, etc...
import org.apache.http.util.EntityUtils;

public class HttpGetRequest {

public static void demo() throws IOException {           
    String consumer_key = "bcd";
    String consumer_secret = "efg";
    String access_token = "rst";
    String access_secret= "xzy";

    OAuthConsumer consumer = new CommonsHttpOAuthConsumer(consumer_key,
consumer_secret);
    consumer.setTokenWithSecret(access_token, access_secret);


    String uri = "your url here";
    HttpClient httpclient = new DefaultHttpClient();
    HttpGet httpget = new HttpGet(uri);
    try {
        consumer.sign(httpget);
    } catch (OAuthMessageSignerException ex) {
        Logger.getLogger(HttpRequest.class.getName()).log(Level.SEVERE,       null, ex);
    } catch (OAuthExpectationFailedException ex) {
        Logger.getLogger(HttpRequest.class.getName()).log(Level.SEVERE, null, ex);
    } catch (OAuthCommunicationException ex) {
        Logger.getLogger(HttpRequest.class.getName()).log(Level.SEVERE, null, ex);
    }
    HttpResponse response = httpclient.execute(httpget);
    System.out.println(response.getStatusLine().toString());
    HttpEntity entity = response.getEntity();
    System.out.println();
    System.out.println(EntityUtils.toString(entity));       
}
public static void main(String[] args) {
    try {
        demo();
    }
    catch(IOException ioe) {
        System.out.println(ioe);
    }
}
}
