public static int[] getIntegers(Object[] array) {
      int[] ret = new int[array.length];
      for (int i = 0; i < array.length; ++i) {
             Object o = array[i];
             if (o instanceof Number) {
                   Number n = (Number) o;
                   ret[i] = n.intValue();
             } else {
                   throw new RuntimeException(o + " is not a number.");
             }
