Understanding useDelimiter in Scanner : why I get blank token?

Question

I\'m using scanner with delimiter and I\'ve came across a strange behaviour I\'d like to understand.

I\'m using this programm :

    Scanner sc = new          


        

Answer 1

I happened to encounter the empty token problem with the Scanner class too. I think the delimiter pattern has to be made greedy by surrounding it with parenthesis and appending + to the group. The pattern I used looks like this

"((\\s)+|(\\\\r\\\\n)+|\\p{Punct}+)+".
