Comparing URLs with parameters in Java

Question

These two urls should be the same:

http://localhost?asdf=1&qwer=2
http://localhost?qwer=2&asdf=1

But using 'equals()' from the URL class, I get that they're different. How can I compare them?

EDIT: Some background on this question

I'm creating a Selenium test for some url mapping. I have old url, url it should get mapped to and the actual url. I need to compare the should-be url to the actual url. List of urls is created by client. Urls with the same parameters and values are considered valid if the list of parameters is the same, and they all have the right values (order of those parameters is irrelevant)

Answer 1

So if I get it right, you want to compare two URL's, regardless of the order of the query part.

There does not seem to be a method for this in the URL class, so you'll have to write your own. Also, URL is final, you cannot override URL.equals(Object).

Your method could start with calling sameFile().
If that evaluates to true, you then call getQuery(), and split it into it's components - probably with String.split("\&"). From there on, you evaluate if the parameters are the same.
Also, don't forget to check if the "#fragment" is equal, if that is important to your application.
