How to find out operating system drive using java?

Question

How can we code in java to find out the drive letter on which operating system is installed ?

Are you aware that there are operating systems that do not follow the "Windows Drive Letter Concept"? Is this supposed to work on Windows only? — reto, Feb 24 '14 at 10:30
@reto not really a duplicate because it uses the win32 api. Can't be called as is from java, you would need a JNI call. — assylias, Feb 24 '14 at 10:33
@assylias you do have a point there, the most voted answer is however referring to the same system env. variable — reto, Feb 24 '14 at 10:37
Once upon a time the operating system used to be on the A: drive but that was long before windows. Do you ever see users installing on a drive other than C: ? — Peter Lawrey, Feb 24 '14 at 10:50

You can get that from the Environment:

System.getenv("SystemDrive");
