Comparing URLs with parameters in Java

These two URLs must be the same:

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

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

EDIT: Some background on this

I am creating a Selenium test for some URL mapping. I have an old url, the url to which it should be mapped, and the actual url. I need to compare the intended URL with the actual URL. A list of URLs is created by the client. Urls with the same parameters and values ​​are considered valid if the list of parameters is the same and they all have the correct values ​​(the order of these parameters does not matter)

, URL-

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

////////EDITED PART//////////

....

- openStream() URL.

- Save both of them as 2 StringObjects or StringBuilder.

- Now compare both of them with equals().

- This will solve the problem, I think so ....
