package test;import java.io.BufferedReader;import java.io.InputStreamReader;import java.net.HttpURLConnection;import java.net.URL;public class HttpTest {  private String u;  private String encoding;  public static void main(String[] args) throws Exception {    HttpTest client = new HttpTest("http://www.baidu.com/", "UTF-8");    client.run();  }  public HttpTest(String u, String encoding) {    this.u = u;    this.encoding = encoding;  }  public void run() throws Exception {    URL url = new URL(u);// 根据链接(字符串格式),生成一个URL对象    HttpURLConnection urlConnection = (HttpURLConnection) url        .openConnection();// 打开URL    BufferedReader reader = new BufferedReader(new InputStreamReader(        urlConnection.getInputStream(), encoding));// 得到输入流,即获得了网页的内容    String line; // 读取输入流的数据,并显示    while ((line = reader.readLine()) != null) {      System.out.println(line);    }  }}
