Scanner : Java Glossary


A class for breaking a stream of characters into tokens using regex expressions to describe where to make the splits. It is also capable of converting the String tokens into ints, longs etc. The source of the data could be a String, a file, an encoded file, or an InputStream or a ReadableByteChannel.

Scanner fills much the same niche as CSV files. I prefer CSV (Comma-Separated Value) to Scanner since it does need to reserve magic separator characters that cannot occur in data.
