  user.country, user.script, sun.java.launcher,  sun.os.patch.level,

  java.vm.specification.name, user.dir, java.runtime.version,

  java.awt.graphicsenv,  java.endorsed.dirs, os.arch, java.io.tmpdir,

  line.separator, java.vm.specification.vendor, user.variant,

      private static void printSystemProperties(){

            Properties properties=System.getProperties();

            String key;

            Enumeration keys=properties.keys();

            while(keys.hasMoreElements()){

                  key=(String)keys.nextElement();

                  System.out.println("\n");

                  System.out.println("key :"+key);

                  System.out.println("value :"+properties.getProperty(key));

            }

Happy coding :)
