这是我写的弄出所有D盘文件名字，想把结果写进txt中，该如何实现？求教！！！

查询，写入都帮你搞定了，给分吧
- Java code
package test;import java.io.File;import java.io.FileOutputStream;public class Search { StringBuffer str = new StringBuffer(); public static void main(String[] args) { try { Search s = new Search(); s.search(new File("D:\\")); String name = s.str.toString(); File file = new File("D:\\name.txt"); FileOutputStream fos = new FileOutputStream(file); fos.write(name.getBytes()); fos.flush(); fos.close(); } catch (Exception e) { e.printStackTrace(); } } public void search(File file) { if (file.isFile()) { str.append(file.getName()); } else { File[] files = file.listFiles(); for (File f : files) { search(f); } } }}

命令行
dir /s/b d: >> f:\files.txt
