获取指定文件夹下的所有文件名

递归获取某目录下的所有文件名，路径。

1 package test; 2 3 import java.io.File; 4 5 public class GetFileName{ 6 7public static void main(String[] args) { 8 // This is the path where the file's name you want to take. 9 String path = "C:\\ProgramData";10 getFile(path);11}12 13private static void getFile(String path) {14 // get file list where the path has15 File file = new File(path);16 // get the folder list17 File[] array = file.listFiles();18 19 if (array != null)//没权限访问，则会报错文件为null20 for (int i = 0; i < array.length; i++) {21 if (array[i].isFile()) {//可以这样判断if(objinstanceofFile){ 22 // only take file name23 System.out.println("^^^^^" + array[i].getName());24 // take file path and name25 System.out.println("#####" + array[i]);26 // take file path and name27 System.out.println("*****" + array[i].getPath());28 } else if (array[i] instanceof File) {29 getFile(array[i].getPath());30 }31 }32}33 }

若要返回这些东西，

则：

package test;import java.io.File;/*** * 获取指定目录下的所有的文件（不包括文件夹），采用了递归 * * @param obj * @return */ public static ArrayList<File> getListFiles(Object obj) { File directory = null; if (obj instanceof File) { directory = (File) obj; } else { directory = new File(obj.toString()); } ArrayList<File> files = new ArrayList<File>(); if (directory.isFile()) { files.add(directory); return files; } else if (directory.isDirectory()) { File[] fileArr = directory.listFiles(); for (int i = 0; i < fileArr.length; i++) { File fileOne = fileArr[i]; files.addAll(getListFiles(fileOne)); } } return files; }
