java使用URLConnection类从Web服务器上读取文件的信息，并将结果打印到控制台

package com.dh.ch13;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;

public class URLConnectionDemo {
	public static void main(String[] args) throws Exception {
		// 构建一URL对象
		URL baidu = new URL("http://www.baidu.com/");
		//由URL对象获取URLConnection对象
		URLConnection uc=baidu.openConnection();
		//由URLConnection获取输入流，并构造BufferedReader对象
		BufferedReader br = new BufferedReader(new InputStreamReader(uc.getInputStream()));
		String inputLine;
		// 循环读取并打印数据
		while ((inputLine = br.readLine()) != null)
			System.out.println(inputLine);
		// 关闭输入流
		br.close();
	}
}
