 How do I pull "7" from the string and convert it to an integer?

StringBuffer digits = new StringBuffer();
char c;
for (int i=0; i
   c = strSEQ.charAt(i);
   if (Character.isDigit(c))
       digits.append(c);
}
int intValue = Integer.parseInt(digits.toString());

 Q: I have a string like 23,N/A,,N/A,87, then I used the StringTokenizer t = new
StringTokenizer( s, ",");
to get the token. I seems I only got 4 tokens back, not 5. How doesStringTokenizer
treat the ,, in this case? I had tried String.equals("") or String.equals(null) to pick the
EMPTY string between ,, , it did not work.
Anyone can give a clue?
Answer: You can tell it to return the delimiters as well as the tokens. When you
receive two consecutive delimiters you know that the token was empty.

There is another constructor, with a third parameter. Using that one, you can get
the boundary markers, such as the comma, returned to you as well. That would allow
you to handle your empty strings.
