java中HttpGet和HttpClient和HttpResponse之间的联系是如何的
每一个对象分别承载着什么信息

解决方案

 public class HTTPGetSample {
    public static void main(String[] args) throws ClientProtocolException, IOException {
        String url = "http://www.google.com.hk/search?q=httpClient";  

        HttpClient client = new DefaultHttpClient();
        HttpGet request = new HttpGet(url);  

        HttpResponse response = client.execute(request);
        System.out.println("Response Code: " +
        response.getStatusLine().getStatusCode());  

        BufferedReader rd = new BufferedReader(
            new InputStreamReader(response.getEntity().getContent()));
        String line = "";
        while((line = rd.readLine()) != null) {
        System.out.println(line);
        }
    }
}

在这个例子中可以看出，HttpGet是我们请求的类型，为GET请求，然后通过HttpClient执行HttpGet请求，返回HttpResponse
