Identify Operating System

System.getProperty("os.name")

Is it possible to identify the family of OS?
I want to know if it windows / mac / linux. But I don't care which version.

String s = System.getProperty("os.name")
if(s.startsWith("Windows")) - this is windows,
but you should run some tests whaat weach system returns

But is there a generic way to figure out the family.
Like in ant, I can do this:

  <condition property="avn" value="avn.bat">
    <os family="windows"/>
  </condition>

I am not sure there is a generic way - and how could it be - someone can come up with some new system
which will do something new

the tests in http://www.mkyong.com/java/how-to-detect-os-in-java-systemgetpropertyosname/
should cover most of the cases, but not guaranteed of faling

Could you answer this question:
