To include special characters such as spaces and quotes in a URL string, you need to encode them. Similarly, you need to decode encoded characters in a URL to recover the original URL. The following code demonstrates how to code/decode a string using the URLEncoder/URLDecoder classes.
import java.net.*;
public class URL_Encoder_Decoder{
public static void main(String[] args){
String sir="@sir de caractere@,nr. 1290 'paragraf 3'";
try{
String sir_codat=URLEncoder.encode(sir,"UTF-8");
String sir_decodat=URLDecoder.decode(sir_codat,"UTF-8");
System.out.println(sir);
System.out.println(sir_codat);
System.out.println(sir_decodat);
}catch(java.io.UnsupportedEncodingException e)
{System.out.println("Eroare:"+e.getMessage());}
}
}
Here's the result:
@sir de caractere@,nr. 1290 'paragraf 3'
%40sir+de+caractere%40%2Cnr.+1290+%27paragraf+3%27
@sir de caractere@,nr. 1290 'paragraf 3'
