Hi,
You can use StringTokenizer which is available in util package. You can specify the token-separator, which, in this case, will be left-open-brace, comma and right-close-brace. It allows you to get the tokens out of the expression.
Once you get the token, you need to perform some priliminary processing as mentioned below:
(a)If you can convert the token to integer, the add it to the target list.
(b) If there is NumberFormatException, then the token string specifies range ex: 7-15. In this case, you need to add a list of values.
I hope this will solve the problem.
