Examples: listing files using wildcards

Using class PathPattern one can list files using wildcards(* and ?) much likely doing it in a shell prompt. For example, "*.txt" is a pattern for txt files in a current directory, and "c:/user/dir/*" lists all in a "c:/user/dir" directory. Note that PathPattern makes no difference between object types(files, directories, links, etc). To run an example, type:
java -cp .;[path to jregex.jar] List "some path with wildcards"

The sample session:

java -cp .;../lib/jregex.jar List "d:\Opera\*.txt"
Listing directory d:\Opera
Install.txt
License.txt
lngcode.txt

3 files found

Source:

import jregex.util.io.*;

public class List{
   public static void main(String[] args){
      if(args.length<1){
         usage();
         return;
      }
      PathPattern pp=new PathPattern(args[0]);
      System.out.println("Listing directory "+pp.directory());
      String[] files=pp.list();
      for(int i=0;i<files.length;i++){
         System.out.println(files[i]);
      }
      System.out.println();
      System.out.println(files.length+" files found");
   }
   
   static void usage(){
      System.out.println("Usage:");
      System.out.println("java -cp .;[path to jregex.jar] List \"PATH\"");
   }
}
