i want to save 2 to variable a, 5 to variable b, and 3 to variable c . .
how i can do that . . ?
tanks for your help . .

How do you know if a number is to go to a variable or not?
Your example skips over the second 2 and the 0?

A regular expression might help you extract the numbers from the String you posted.
Also the StreamTokenizer class could work.
