Try   System getProperty  os name      http   docs oracle com javase 7 docs api java lang System html getProperties 28 29

You can use  system properties os   for example   public class GetOs      public static void main  String   args        String s           name      System getProperty   os name        s       version      System getProperty   os version        s       arch      System getProperty   os arch        System out println   OS     s             EXAMPLE OUTPUT  OS name  Windows 7  version  6 1  arch  amd64   Here are more details    http   docs oracle com javase tutorial essential environment sysprop html

I think It s a best approach to use Apache lang dependency to decide which OS you re running programmatically through Java  import org apache commons lang3 SystemUtils   public class App       public static void main  String   args             if SystemUtils IS OS WINDOWS 7              System out println  It s a Windows 7 OS            if SystemUtils IS OS WINDOWS 8              System out println  It s a Windows 8 OS            if SystemUtils IS OS LINUX              System out println  It s a Linux OS            if SystemUtils IS OS MAC              System out println  It s a MAC OS
