Question

I’d like to convert PHP code to Java, that is to decode a string stored as an encoded URI format.

That is, change

This%20is%20a%20%2Burl%2B%21

into

This is a +url+!

I’ve looked at java.net.URI, but there are no suitable examples, and it seems that anything to be decoded by it needs to be in a proper URI format. I’d like to convert a string that isn’t in proper format, but contains HTML encoding.

Answer 1

java.net.URLDecoder.decode("This%20is%20a%20%2Burl%2B%21", "UTF-8");

UTF-8 is of course just an example. Use whatever your input encoding is.
