how to use and test a stemmer in NetBeans?

capricy32

I'd like to test a stemmer (Porter) on some text to see how it works. Don't know how to approach it. I use Netbeans. I copy-pasted the open-source stemmer into a new created (main) class in a new project. But how I test this (method?) on some text?

Hope this sound understandable. Thx for reply!
