java如何获取ftp制定目录下所有文件集合(包括文件名称)只要一个方法。,第1张

/**

我从这里拷来的 你不清楚看看里面 http://hi.baidu.com/yuanhotel/item/000b6334894d11f42784f4da

满意皮简码就采纳 谢谢

package com.hmilyld.exp

import java.io.File

public class ListFile {

private long[] count = new long[] { 0, 0 }

private File file

private long[] listFile(String path) {

file = new File(path)

File[] f = file.listFiles()

for (int i = 0i <f.lengthi++) {

if (f[i].isDirectory()) {

count[0]++

this.listFile(f[i].getPath())

} else {

count[1]++

}

}

return count

}

/**

* 得到指定路径下的文件和文件夹数量

*

* @param path

*要查看的路径

* @return object[0]耗时(毫秒)<br>

* object[1]文件夹数量<br>

* object[2]文件数量

*/

public Object[] getFileCount(String path) {

long t = System.currentTimeMillis()

long[] count = this.listFile(path)

t = System.currentTimeMillis() - t

Object[] o = new Object[] { Long.valueOf(t), Long.valueOf(count[0]),

Long.valueOf(count[1])}

return o

}

public static void main(String[] args) {

ListFile l = new ListFile()

Object[] count = l.getFileCount("d:\\")

System.out.println(count[0])

System.out.println(count[1])

System.out.println(count[2])

}

}

以前轮迅写的一个获取目录下有多少文件和多少文件夹的漏桐谈代码,

可以参考下返碰.:)
