How can I read only text files in a directory.

2801625

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();

  }

  }

  }

  }

  }

}

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
          }

Inside you loop you could get the file name using

textfiles.getName();

You could filter with the file extension.

Can you explain what you mean by filter with the file extension.

I was able to read only the text files in the directory checking the extension using textfiles.getname and textfiles.endswith.

Thanks for the help AJ.

     for (File textfiles : files) {

     if (textfiles.isFile() && textfiles.getName().endsWith("txt")) {
