FilenemeFiler 类怎么用啊？用他怎么遍历一个文件夹下的所有文件呢?

[anmeier]

对不起FilenameFileter写错了

参考一下：

import java.io.*;

public class ListDirectory {
public static void main(String[] args) {
String[] list;
File path = new File(".");
if (args.length > 0) {
list = path.list(new SimpleFilter(args[0]));
} else list = path.list();
for (int i = 0; i < list.length; i++)
System.out.println(list[i]);
System.out.println("合计" + list.length + "个文件。");
}
}
class SimpleFilter implements FilenameFilter {
String pattern;
SimpleFilter(String pattern) {
this.pattern = pattern;
}
public boolean accept(File dirName, String fileName) {
return (fileName.indexOf(pattern) >= 0);
}
}
