import java.net.URL;

public class MyClass {
    public static String doHTTPGETRequest(String url) throws Exception {
        URL obj = new URL(url);
        
        HttpURLConnection con = (HttpURLConnection) obj.openConnection();

        con.setRequestMethod("GET");

        BufferedReader br = new BufferedReader(
        new InputStreamReader(con.getInputStream()));
        
        String HTMLLine;
        StringBuilder response = new StringBuilder();
    
        while ((HTMLLine = br.readLine()) != null) {
            response.append(HTMLLine);
        }
        br.close();
        
        return response.toString();
    }
    public static void main(String args[]) throws Exception {
