import java.io.File;
import java.util.Collection;

import org.apache.commons.io.FileUtils;
import org.apache.commons.io.filefilter.IOFileFilter;


public class SearchDocFiles {
    public static String[] EXTENSIONS = { "doc", "docx" };

    public Collection<File> searchFilesWithExtensions(final File directory, final String[] extensions) {
         return FileUtils.listFiles(directory,
                                    extensions,
                                    true);
     }


    public static void main(String... args) {


         Collection<File> documents = new SearchDocFiles().searchFilesWithExtensions(
                    new File("/path/to/document/folder"),
                    SearchDocFiles.EXTENSIONS);
            for (File document: documents) {
                System.out.println(document.getName() + " - " + document.length());
            }
        }
    }

this uses Apache Commons IO expectially FileUtil
