一、試題描述

獲取指定目錄（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 );}// 通過遞歸得到某一路徑下所有的目錄及其文件static void getFiles( String pathname ){File root = new File( pathname );File[] files = root.listFiles();System.out.println(pathname+"目錄下的所有文件名為：");for (File file : files){if ( file.isDirectory() ){// 遞歸調用getFiles( file.getAbsolutePath() );filelist.add( file.getAbsolutePath() );System.out.println( file.getAbsolutePath() );}else{System.out.println(file.getAbsolutePath() );} //else} //for} //getFiles() }

三、執行結果

E:/Datasets/Ukbench100目錄下的所有文件名為：
