How to get a part of URL String

I am new to Java. I have a String URL as follows:

http://ift.tt/1fveTmx/42?param=true

I want to retrieve a part of this string. I don't want the last part in the URL and want to retrieve the path foo/bar/. I don't want domain name and last part(here 42).

Could you please let me know the best way to achieve this?

Thanks
