Before I step in early.

Hey everyone on this forum, or rather just the ones reading this post!
So, heres the deal and I hope someone may be able to help me here: I want to start learning Java for self coding purposes, and I will be taking a Java class senior year, but I want to start early. I had an interesting idea for an application, but I need to know first if maybe Java isn't the right choice. Would an application built in Java be able to theoretically delete the contents of a folder placed anywhere on a computer by simply being pointed to such file, and also on a timed basis? This part is only a section of the application I want to build, but I saw somewhere while googling for some self learning sites that Java is not able to point to directories... Maybe I was misinformed? Now I can't cite this source, cause I already lost it while jumping site to site picking up small details about the language... But hopefully someone here can set me straight? Thanks in advance!

A Java Applet (which resides on a server, and runs on a web page in a browser in the client computer) can't access the local filesystem unless signed/trusted.

A Java application which resides on the same computer on which it is run, has no such limitations.

Yes.

Okay, so creating a Java application, the application would be able to do what I want.. but after building this application I could just distribute the program via a download and have the application work as intended?
(Sorry if this sounds stupid, I realize the question is probably a common "duh", just making sure :D)

Yes, yes you could. However be mindful of the obvious. Assuming the data you wish to delete is contained in the same directory path can cause issues with different operating systems, even between different versions of Windows.

<pedant>Well, a Web Start application is a desktop app that has the same restrictions as an Applet.</pedant>

Mkay, thanks for the help everyone, looks like I'm gonna stick to Java after-all :D
Probably gonna keep using this forum for help along the way as well ^___^
