Question

I am importing this following :

import org.apache.lucene.analysis.PorterStemmer

in Java program. The whole package is available in refrenced library.

I tried importing

import org.apache.lucene.analysis.PorterStemFilter

and

import org.apache.lucene.analysis.Analyzer;

both are working fine except the first one mentioned
Can anybody point out why ?!

Answer 1

Package org.apache.lucene.analysis.PorterStemmer is not a public package which is why you cannot import it. If you look at this package inside the library, you’ll notice that it begins with class PorterStemmer instead of public class PorterStemmer.
