How to get a single file from a folder in java? -

-

The idea is to take a file, but I do not want to list all the files. I have the address of the folder specified, but the name is not.

Actually I want

findFileInFolder (string folder name) --- this method returns a random file name or created on the old file folder

Has anyone ever tried to do this?

Added:

In the case of the bus I was not clear (I'm doing) really sorry for my English. Please forgive me if I make a motivational or aggressive sound, in fact, this is not my intention.) File is not selected by any person, it is chosen without any request by the machine or showing the file string With filename

string fail infaller (string folder name)

As I am commenting about the use of RAM and processor because it is a secondary form Process and is not the primary of the project, so if I have to read one thousand files, which will greatly reduce the performance of my project: (

thanks;)

Update: The program is running on different computers, so I could simply access the directory that does not "think" about reading, which would be very good to file. = D

Hope is last updated: you are sorry to bother people :)

There is no way from the answers I read. My question is: Do you think that instead of doing an array, what would be the best option? I think creating an index in the text file and taking only the first line.

You can do this on class and

Will be able to filter for example according to their last modified date.

On one side of the note, why do you want to avoid the list of all files for performance issues?

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
