Just edit your code like this,

public ArrayList ReadDirectory() {
        String path = "C://Documents and Settings/myfileTxt";

        ArrayList files = new ArrayList();
        File folder = new File(path);
        File[] listOfFiles = folder.listFiles();

        for (int i = 0; i < listOfFiles.length; i++) {
            if (listOfFiles[i].isFile()) {
                files.add(listOfFiles[i].getName());
                if (files.endsWith(".txt") || files.endsWith(".TXT")) {
                    System.out.println(files);
                }
            }
        }
        return files;
    }

Which will return ArrayList object and then you can convert that ArrayList object to a normal array.

Something like this, Lets say your variable name is,

ArrayList listData = new ArrayList();

Just do this to convert it into normal array,

listData.toArray();
