获取指定目录下的所有文件名

一、试题描述

获取指定目录（例如"E:/test"）下的所有文件名

二、Java程序

import java.io.File;
import java.util.ArrayList;

public class DirectoryFileName {
    private static ArrayList<String> filelist = new ArrayList<String>();

    public static void main(String[] args) throws Exception
    {
        String pathname = "E:/Datasets/Ukbench100";
        getFiles( pathname );
    }

    // 通过递归得到某一路径下所有的目录及其文件
    static void getFiles( String pathname )
    {
        File root = new File( pathname );
        File[] files = root.listFiles();
        System.out.println(pathname+"目录下的所有文件名为：");
        for (File file : files)
        {
            if ( file.isDirectory() )
            {
                // 递归调用
                getFiles( file.getAbsolutePath() );
                filelist.add( file.getAbsolutePath() );
                System.out.println( file.getAbsolutePath() );
            }else{
                System.out.println(file.getAbsolutePath() );
            } //else
        } //for
    } //getFiles()
}

三、执行结果

E:/Datasets/Ukbench100目录下的所有文件名为：
