JAVA SE x86 or x64?

Question

So this is probably a stupid question but I need to start working on a JAVA application and I should update my jdk I presume. So I go to the website and it has Windows x64 and x86 downloads.

My question is this. I have a 64-bit system, but my Program Files is x86. So does that mean I should use a x86 jdk or x64? I guess I am confused on why my program files folder has a different size than my system itself, or is my system x86?

I hope you can see my silly confusion on this matter.

Thank you, -Austin

Solution

Download the x64 version since it's designed for the computer with your architecture. You have x86 Program Files folder only for application which can't run under 64bit environment. It's basically just backward compatibility.
