extracting digits from a number using stringTokenizer

Question

given a number (user input) 01111000

I want to extract the individual digits 0,1,1,1.....

Is it possible using stringtokenizer, I have tried empty strings, "//d" , "?" but it doesn't work...

specific to stringtokenizer only

please please answer if it is possible using stringtokenizer only — Creative_Cimmons, May 28 '15 at 16:06
Why do you want to use StringTokenizer for something that is better done in other ways? Also, from the Javadoc - "StringTokenizer is a legacy class that is retained for compatibility reasons although its use is discouraged in new code. It is recommended that anyone seeking this functionality use the split method of String or the java.util.regex package instead." — Phil Anderson, May 28 '15 at 16:08
But StringTokenizer just retruns Strings. There's absolutely no need to use StringTokenizer instead of other options like String.split that would also return Strings. — Phil Anderson, May 28 '15 at 16:12

String s = "01111000";
System.out.println(java.util.Arrays.toString(s.split("(?<=\\G.)")));

Which produces

[0,1,1,1,1,0,0,0]

Why Tokenizer? Use a loop and a charAt(position).

If you still want Tokenizer, use this trick:

String number = "01111000010".replaceAll("", " ");
StringTokenizer tokens = new StringTokenizer(number," ");
