Decode ASCII characters inside a String

Question

I am looking for a Java instruction to convert

http://dbpedia.org/resource/NVA_%28film%29

to

http://dbpedia.org/resource/NVA_(film)

Answer 1

Try this

URLEncoder.encode("http://www.your-url.com, "UTF-8");

and this to reverse

URLDecoder.decode(encodedString, "UTF-8");

Answer 2

I'm not aware, offhand, of easy way to do this with just the JDK classes, but Apache Commons Codec has a useful URLCodec utility:

String url = "http://dbpedia.org/resource/NVA_%28film%29";
URLCodec codec = new URLCodec();
String decodedURL = codec.decode(url);
