You can create a temporary file in the default temporary file directory or a directory of your choice.

It accepts a prefix which is at least three characters in length and a suffix to generate the temporary file name.

      boolean fileCreated = tempFile.exists();
      System.out.println(fileCreated);
    } catch (IOException e) {
