Here is one more way i used with Java8

String dateTime= DateTimeFormatter.ofPattern("yyyyMMddHHmmss").format(ZonedDateTime.now());
String fileName = String.format("Clear-%s.DAT", dateTime);
Path filePath = FileSystems.getDefault().getPath("D://FILEPATH//", fileName);
Files.createFile(filePath);

First, get the date and time as a String formatted correctly. You can use SimpleDateFormat. And you can use the File(File, String) constructor to give your File the correct folder. Then you might use a PrintStream(File) to print something. And a try-with-resources Statement to clean-up. Finally, you could put that all together into something like

DateFormat df = new SimpleDateFormat("yyyyMMddHHmmss");
File folder = new File("D://FILEPATH");
File f = new File(folder, String.format("Clear-%s.TXT", df.format(new Date())));
try (PrintStream ps = new PrintStream(f) {
    ps.println("Hello, File!");
} catch (IOException e) {
    e.printStackTrace();
}

Date date = new Date() ;
SimpleDateFormat dateObject = new SimpleDateFormat("yyyy-MM-dd HH-mm-ss") ;
File yourTextFile = new File(dateObject.format(date) + ".tsv") ;
BufferedWriter result = new BufferedWriter(new FileWriter(yourTextFile));
result.write("Writing content");
out.close();

Try with above code. It will create a file with the current date and time.

Try to create file name with date from the very beginning. Plus, it would be great to choose date and time format that you are going to use.
