Decoding URI query string in Java

Question

I need to decode a URI that contains a query string; expected input/output behavior is something like the following:

abstract class URIParser
{       
    /*         


        

Answer 1

new java.net.URI(proxyRequestParam).getPath()

The string encoded by js encodeURIComponent should just be a path, without schema and other things. However it still a valid input for java.net.URI. So java.net.URI will do everything for us and then the path of it is what we want.
