It would be better if you can maintain a Set (Avoid Duplicates) for all files you create.

And iterate the file list and delete every file one by one.

 public static final Set TMP_FILES = new HashSet<>();

And delete all by iterating.

public void deleteTempFiles() {
  for(String myTempFile: TMP_FILES) {
    try {
      new File(myTempFile).delete();
    } catch (Exception e) {
      // Handle if needed.
    }
  }
}
