I have a spinner for Period which contains the selections:

3 months
6 months
10 months
12 months
18 months

PROBLEM:

I can get the value of the spinner selection but I need a way to get just the numerical value of the selection ( i.e. just the 3 from 3 months ) for use in another activity with calculations using BigDecimal. Can anyone guide me accordingly?

The code below will replace all non digits and you will get inly integer value.

String s = spinner.getSelectedItem().toString();

int spinnerVal = Integer.parseInt(s.replaceAll("[\\D]", ""))

  • Found the same answer [here](http://stackoverflow.com/questions/10372862/java-string-remove-all-non-numeric-characters) the same time you answered haha, I'll accept your answer as soon as that accepting timer goes, thanks :) – Cai Mar 15 '15 at 15:33

    @Astatine0936 no the answers are **not** same!! But the output will be same indeed. The answer link you have posted says, `replaceAll("[^\\d.]", "");` where `^` means `not` and `d` means `digits` while my answer is `replaceAll("[\\D]", ""` where `D` itself means **`non digit`**. So the answer is NOT a copy. – Apurva Mar 15 '15 at 15:41
  • Ahh, so that's what the lower and upper case stand for. Thank you very much for the clarification, I will definitely remember that in the future. In any case I used your code above anyway so everything is working perfect now. Again thank you very much :) – Cai Mar 15 '15 at 15:51
