本文展示了一个使用Apache HttpClient库进行HTTP GET请求并解析响应内容的基本示例，具体包括URL构造、连接创建、输入流获取及UTF-8编码的字符读取。

package demo1;

import java.io.*;
import java.net.*;

import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.HttpResponseException;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;

public class Test1 {
	public static void main(String[] args) throws ClientProtocolException, IOException {
		URL url=new URL("http://www.baidu.com");
		HttpURLConnection httpurlconnection=(HttpURLConnection) url.openConnection();
		InputStream is=httpurlconnection.getInputStream();
		
		
		BufferedReader breader=new BufferedReader(new InputStreamReader(is,"utf-8"));
		String line="";
		while((line=breader.readLine())!=null)
		{
			System.out.println(line);
		}
	}

}
