读取当前工作空间文件名：

代码：

 1 package io;
 2 
 3 import java.util.regex.*;
 4 import java.io.*;
 5 import java.util.*;
 6 
 7 public class DirList2 {
 8     public static FilenameFilter filter(final String regex){
 9         return new FilenameFilter(){
10             private Pattern pattern = Pattern.compile(regex);
11             public boolean accept(File dir,String name){
12                 return pattern.matcher(name).matches();
13             }
14         };
15     }
16     public static void main(String[] args){
17         File path = new File(".");
18         String [] list;
19         if(args.length ==0)
20             list = path.list();
21         else
22             list = path.list(filter(args[0]));
23         Arrays.sort(list,String.CASE_INSENSITIVE_ORDER);
24         for(String Item: list)
25             System.out.println(Item);
26     }
27 }

结果：

1 .classpath
2 .project
3 .settings
4 bin
5 DirList2.java
6 src
