public static String getUrlResponse(String url) {
        try {
            HttpGet get = new HttpGet(url);
            HttpClient client = new DefaultHttpClient();
            HttpResponse response = client.execute(get);
            HttpEntity entity = response.getEntity();
            return convertStreamToString(entity.getContent());
        } catch (Exception e) {
            return null;        
          }
        return null;

object-c 的异常构造，并抛出

    @try {
        NSException *exception = [NSException exceptionWithName: @"HotTeaException"
                                                         reason: @"The tea is too hot"

        @throw exception;
    }
    @catch (NSException *exception) {
        NSLog(@"main: Caught %@: %@", [exception name], [exception reason]);
    }
    @finally {
        NSLog(@"finally");
    }
