使用jdk提供的类完成URL的编解码

public class UrlDemo {     
         public static void main(String[] args) throws Exception {                  
                   /**
                    * URLEncoder: 进行URL编码
                    */
                   String encode = URLEncoder.encode("张三", "utf-8") ;           // %E5%BC%A0%E4%B8%89
                   System.out.println(encode);               
                   System.out.println("----------------------------------------------");        
                   /**
                    * URLDecoder: 进行解码
                    */
                   String result = URLDecoder.decode(encode, "utf-8") ;
                   System.out.println(result);               
         }
}
