Prepare post data,
String data = URLEncoder.encode("key1", "UTF-8") + "=" + URLEncoder.encode("value1", "UTF-8");
data += "&" + URLEncoder.encode("key2", "UTF-8") + "=" + URLEncoder.encode("value2", "UTF-8");Creat connection,
URL url = new URL("http://hostname/");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);Send data
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(data);
wr.flush();If you need to get the response do the following
BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        String line;
        while ((line = rd.readLine()) != null) {
            // Process line...
        wr.close();
        rd.close();
