design a async Networking Library in Java

* You have to design a async Networking Library in Java named myHttp (basically wrapper over HttpURLConnection), * the library should expose the following interface. */ /** * [login to view URL] API example of GET request. * String: methodType * String: url * Map<String, String>: headers * String: tag */ ListenableFuture<myResponse> getResponseFuture = [login to view URL](new OfbRequest(GET, url, headers, tag)); [login to view URL](getResponseFuture, new FutureCallback<OfbResponse>() { public void onSuccess(myResponse ofbResponse) { //process response asynchronously } public void onFailure(Throwable thrown) { //process failure } public void onCancel() { //process cancellation }}); /** * [login to view URL] API example of POST request. * String: methodType * String: body * String: url * Map<String, String>: headers * String: tag * */ ListenableFuture<myResponse> postResponseFuture = [login to view URL](new myRequest(POST, body, url, headers, tag)); [login to view URL](postResponseFuture, new FutureCallback<myResponse>() { public void onSuccess(myResponse myResponse) { //process response asynchronously } public void onFailure(Throwable thrown) { //process failure } public void onCancel() { //process cancellation }}); /** * [login to view URL] API example of GET request * This will cancel all the requests with the provided "tag" and call their onCancel callback */[login to view URL](tag); /** * Notes: * If multiple GET requests hit the same url. Then all of the callers should get same response. * * ListenableFuture is a class from guava library * [login to view URL] *
