static arraylist <double> heights = new arraylist <double>();  public static void main(string[] args) {      //use  use method     addsomeheight(5.1);     addsomeheight(6.2);     addsomeheight(6.3);     addsomeheight(5.4);     addsomeheight(5.5);     addsomeheight(5.6);     addsomeheight(5.7);     addsomeheight(5.8);     addsomeheight(5.9);     addsomeheight(6.9);      //declare new method } private static void addsomeheight(double x)  {      (double x1 : heights){         system.out.println(x1);         } } }

you're not adding value list, it's empty. method addsomeheight() doesn't add argument list. ignores it, , prints list instead.

please respect java naming conventions: variables start lowercase letter, , methods camelcased.
