how can I tell in java if the program is running on a windows or linux machine?

Question

Is there a way to tell in Java if the program is running on a Windows or Linux machine? I have a .jar file that I want to run on both.

I'd be very surprised if this question hasn't been asked before. — Mitch Wheat, Nov 23 '13 at 05:12

You can get the os type using

System.getProperty("os.name")

VonC's answer

public static final class OsUtils
{
   private static String OS = null;
   public static String getOsName()
   {
      if(OS == null) { OS = System.getProperty("os.name"); }
      return OS;
   }
   public static boolean isWindows()
   {
      return getOsName().startsWith("Windows");
   }

   public static boolean isUnix() // and so on
}
