After declaring package of class, import classes ExtensionFilenameFilter and FileComparator.

Considering class ExtensionFilenameFilter is present in package a

and FileComparator in b.c, write:

package your_package_name;

import a.ExtensionFilenameFilter;
import b.c.FileComparator;

... //Rest of code.

Read official Java doc.
