java.io.File.list() giving different order as the folders created sequentially

Question

While creating the Temporary folders with name as

"Temp" + auto-incremented number 
e.g. Temp1, Temp2, Temp3...Temp10, Temp11 and so on.

But when I use java.io.File.list() to get the folder list to further processing in order as the folder created,

but its giving as Temp1, Temp10, Temp11...Temp19, Temp2, Temp20, Temp21 and so on.

I also tried Arrays.sort(files); but no change in order of folder list

Please tell how to get the same order list as the folders created sequentially?

The default sort would be lexicographic; implement a [Comparator](http://docs.oracle.com/javase/6/docs/api/java/util/Comparator.html). — devnull, Jan 22 '14 at 05:54
The order in which `File#listFiles` returns `File`s will based on how the OS/native libraries decide the directory listing should be made. — MadProgrammer, Jan 22 '14 at 06:20

It's because the way how java compares strings by default in java (lexicographic order). You can define your own comparator for File objects and sort.
