JAVA or .NET

First things first, can you program?

Each has it's strengths and weaknesses, making the more suited to specific tasks. Quite obviously ASP is pretty strong in the web arena.

Microsoft.net is a frame work, it does have a language but I suspect you are going to choose one of the higher level ones that sists on top.

That's C#, VB. C++, Python, Ruby, ECMA (javscript basically)or F#, last I saw.

C# would be my starter language, but if you haven't done much programming C or Pascal are better choices to learn the fundamentals.
