Java: Programatic Way to Determine Current Windows User

I see many similar questions, however I want to find the Username of the currently logged in user using Java.

Its probably something like:

System.getProperty(current.user);

But, I'm not quite sure.

The commonly available system properties are documented in the System.getProperties() method.

As Chris said "user.name" is the property to get the user running your app.
