思路:
根据天气编码url获取2地天气;
运用StringSteamBuffer读取获取内容;
1 package method; 2 import java.io.BufferedReader; 3 import java.io.InputStreamReader; 4 import java.net.URL; 5 /* 6 功能:获取北京和张北的天气 7 */ 8 public class WeatherReport { 9 public static void main(String args[]) throws Exception{ 10 try{ 11 //由网址创建URL对象 12 URL urlBJ = new URL("http://www.weather.com.cn/data/cityinfo/101010100.html"); 13 URL urlZB = new URL("http://www.weather.com.cn/data/cityinfo/101090303.html"); 14 //“UTF-8”这是为了防止乱码 15 InputStreamReader isReaderBJ = new InputStreamReader(urlBJ.openStream(),"UTF-8"); 16 InputStreamReader isReaderZB = new InputStreamReader(urlZB.openStream(),"UTF-8"); 17 //采用缓冲式读入 18 BufferedReader br_BJ = new BufferedReader(isReaderBJ); 19 BufferedReader br_ZB = new BufferedReader(isReaderZB); 20 String str_BJ; 21 String str_ZB; 22 23 System.out.println("北京天气:"); 24 while((str_BJ = br_BJ.readLine()) != null){ 25 System.out.println(str_BJ);//输出 26 } 27 28 System.out.println("张北天气:"); 29 while((str_ZB = br_ZB.readLine())!= null){ 30 System.out.println(str_ZB); 31 } 32 33 //网上资源使用结束后,数据流及时关闭 34 br_BJ.close(); 35 br_ZB.close(); 36 isReaderBJ.close(); 37 isReaderZB.close(); 38 } 39 catch(Exception exp){ 40 System.out.println(exp); 41 } 42 43 } 44 }
