public static void main(String[] args) throws Exception {
HttpTest client = new HttpTest("", "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

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);
}
}
}
根据具体问题类型 ， 进行步骤拆解／原因原理分析／内容拓展等 。
