private boolean isArchive(File file){
  String n=StringUtils.toLowerCase(file.getName());
  return fsInfo.isFile(file) && (n.endsWith(".jar") || n.endsWith(".zip"));
}

private boolean isArchive ( File file ) { String n = StringUtils . toLowerCase ( file . getName ( ) ) ; return fsInfo . isFile ( file ) && ( n . endsWith ( ".jar" ) || n . endsWith ( ".zip" ) ) ; }
is this the name of an archive file ?
