The above code is excerpted from the Lucene org.apache.lucene.util.Constants class

Alternatively, you can use the following method:

private static String OS = System.getproperty ("Os.name"). toLowerCase ();/** * Determine if Windows * * @return */public static bool Ean Iswindows () {return os.indexof ("Win") >= 0;} public static Boolean Ismac () {return (Os.indexof ("Mac") >= 0);} public static Boolean Isunix () {return (Os.indexof ("Nix") >= 0 | | Os.indexof ("Nux") >= 0 | | Os.indexof ("Aix") > 0);} public static Boolean Issolaris () {return (Os.indexof ("SunOS") >= 0);}
