How to deal with query that works like dir or ls

Question

I just can't figure it out how to deal with query that works like dir (Win32) or ls(unix) with special character like '*' and '?' , ex. c:\> dir j*.t?t
Could somebody please tell me?

Here's some code for using a FileFilter for the listFiles() method of the File class:
import java.io.*;
    FileFilter myFileFilter = new MyFileFilter("*.t?t");
    File[] files = File.listFiles(myFileFilter);
  class MyFileFilter implements FileFilter {
        private String pattern;
        public MyFileFilter(String pattern) {
            this.pattern = pattern;
        public boolean accept(File file) {
            if (file.isDirectory()) {
                return false;
            if (file.getName() ??matches?? pattern) {
                // you'll have to put the pattern match code here!!
                return true;
            return false;
  }maybe someone else can help with the pattern matching!
