  • Take a look at this [link](http://stackoverflow.com/questions/13216432/java-searching-file-name-from-the-one-folder) – Abdelhak Nov 27 '15 at 20:32
  • Duplicate shows you where you should put your filter, but if you are still struggling with how to select only files with structure `oneOrMoreNumber.txt` you could use `return name.matches("\\d+\\.txt");` – Pshemo Nov 27 '15 at 20:43
  • The answer that I found is this : public boolean accept(File directory, String fileName) {return (fileName.endsWith(this.fileExtension)); } but this is not usefull for me because all of my files end with txt, and I want to filter by name..and when I want to print fileName or change it to ArrayList there are some errors.. – avishan sharafi Nov 29 '15 at 17:16
