Hi,everyone,i have trouble with following code,which is for listing all file in
a filepath
public static ArrayList<File> ListFile(File filepath) {
ArrayList<File> fileList = null;
File[] file = filepath.listFiles();
for (File f:file) {
if(f.isFile())
fileList.add(f);
if (f.isDirectory())
ListFile(f);
}
return fileList;
}
Thanks !
