How can I read only text files in a directory.

Question

I've written a program to read files in a directory but I'd like for it to only read the text files of that directory.
import java.io.*;
public class Data {
  public static void main(String[] args) throws IOException {
  String target_dir = "C:\\files";
  File dir = new File(target_dir);
  File[] files = dir.listFiles();
  for (File textfiles : files) {
  if (textfiles.isFile()) {
  BufferedReader inputStream = null;
  try {
  inputStream = new BufferedReader(new FileReader(textfiles));
  String line;
  while ((line = inputStream.readLine()) != null) {
  System.out.println(line);
  } finally {
  if (inputStream != null) {
  inputStream.close();

Answer 1

You have mentioned you want to read only text files.
If you are referring to some specific set of extentions, you can filter based on that.
ex: you want to read only .txt files, you can add an if condition as below :
          if(textfiles.getName().endsWith(".txt")) {
              // Add your code here
