String Tokenizer or Regex

[Ashwath Rangan]

I need to read text from a CSV file where i use "|" as seperators. I am wondering if i should be using String Tokenizer or Regular expressions. Can any body help me in deciding wich is faster.

Thanks in advance

Regular Expression are faster.

Thanks and Regards,

It doesn't matter whether StringTokenizer or split() is faster; neither one is the right tool for this job. For standard CSV data, I would recommend a dedicated CSV parser/tokenizer, but it sounds like Stephen Ostermiller's StringTokenizer replacement will suit your needs better:

If you are reading from files (as in FileInputStream() or FileReader()) then java.io.StreamTokenizer is another possibility if the parsing is reasonably simple.
