+ * Method that assembles all the numbers, form the passed string and
returns them as list.
+ * It is important to note here, is that bu 'number' method assume any
digit sequence, that
+ * can (but not necessary at all) contains dot within it (I mean just
plain old floats,
+ * something like 51.82)
+ *
+ * For example, you may pass a string "21.2 days 3 minutes 22 seconds".
For this particular string
+ * the result list of doubles will look like this : [21.2, 3.0, 22.0]
+ *
+ * if string contains invalid numbers (for example this string contains
+ * not valid number: "My height is 1234.23.13" This is invalid because it
+ * is not clear how to parse this part - 1234.23.13), {@link
NumberFormatException}
+ * will be thrown. Though if string will contain number, where right
+ * after second dot resides not a number, or, any other char, then this
+ * case will be considered as valid. For example, this string contains
+ * only valid numbers: "My pulse is 90.123. and weight is 78.2"
+ * In this case sequence "90.123." will be considered as "90.123", as well
as
+ * sequence "90." (imagine that there is no digit right after dot) will be
+ * considered as 90.0 double.

+ * @param stringThatContainsNumbers - string, that contains number or
several numbers.
+ * Not necessary integers, may be numbers
with float point.
+ * @return - list of numbers, that this particular string contains
+ *
+ * @throws NumberFormatException - see documentation clarification about
cases when thrown above

Review comment:
So, ok, and what is exactly your proposition?) Btw all the types you
mentioned extends Number class, that`s why from my point of view it is valid.
Explain please more to me why it does not work
