Java - get "program files" path

Question

How can I get the current computer's "Program Files" path with Java?

Answer 1

Simply by calling System.getenv(...)

System.getenv("ProgramFiles"); 

Notice it will only work in Windows environments, of course :-)

Answer 2

System.getenv("%programfiles% (x86)");  

for the 32-bit folder on 64-bit PC's.

Also, it works on any language in Windows Vista and newer. Calling either of the posted responses will work on any language installation, in fact.
