使用FilenameFilter对文件进行过滤

使用FileFilter实现对文件的过滤，见代码：

package com.babyDuncan.File;

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

public class testFileFliter {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		File f = new File ("D:/");
		MyFielFilter mff = new MyFielFilter();
		String [] files = f.list(new MyFielFilter());
		for(String s : files){
			System.out.println(s);
		}		
	}
}

类：

package com.babyDuncan.File;

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

public class MyFielFilter implements FilenameFilter{

	@Override
	public boolean accept(File dir, String name) {
		// TODO Auto-generated method stub
		return name.endsWith(".txt");
	}
}

亲测好用!
