import java.io.File;
import java.io.FilenameFilter;


public class OpenFiles {
    public static void main(String[] args){
        File file = new File("C:\\MyDir");
        String[] files = file.list(new FilenameFilter(){
            public boolean accept(File dir,String name){
                return name.endsWith(".txt");
            }
        });
        for(int i=0;i<files.length;i++){
            System.out.println(files[i]);
        }
    }
