This tip shows you how to encode and decode your URLs using the UTF-8 character encoding:

import java.net.*;public class URL_Encoder_Decoder{	public static void main(String[] args){      String url = "@sir de caractere@,nr. 1290 'paragraf 3'";      try{         String encode_url=URLEncoder.encode(url,"UTF-8");         String decode_url=URLDecoder.decode(encode_url,"UTF-8");         System.out.println(url);         System.out.println(encode_url);           System.out.println(decode_url);               }catch(java.io.UnsupportedEncodingException e)              {System.out.println("Error:"+e.getMessage());}            	}}Output:@sir de caractere@,nr. 1290 'paragraf 3'%40sir+de+caractere%40%2Cnr.+1290+%27paragraf+3%[email protected] de caractere@,nr. 1290 'paragraf 3'
