sis.util.IOUtil

 package sis.util; import java.io.*; public class IOUtil {    public static boolean delete(String... filenames) {       boolean deletedAll = true;       for (String filename: filenames)          if (!new File(filename).delete())             deletedAll = false;       return deletedAll;    } } 

The delete method uses varargs to allow you to delete multiple files in a single method call. It returns true only if all files were successfully deleted.
