Scanner OCJP Objective?

[Markus Schmider]

Hello should I learn to work with the scanner class for Java 8 OCJP (1Z0-809)
I have encountered on question concerning the Scanner class in a Kaplan (Transcender) mock exam.

Markus,
No. The following topics topics were on the OCP 7, but removed in the OCP 8. Regular expressions was one of my favorite topics so I was sad to see it go. Luckily streams/lambdas as replaced it as one of my new favorite exam topics.

String Processing
- Search, parse and build strings (including Scanner, StringTokenizer, StringBuilder, String and Formatter)
- Search, parse, and replace strings by using regular expressions, using expression patterns for matching limited to: . (dot), * (star), + (plus), ?, \d, \D, \s, \S, \w, \W, \b. \B, [], ().
- Format strings using the formatting parameters: %b, %c, %d, %f, and %s in format strings.

I mention that it used to be on the exam because that explains why you saw it in a practice exam. Some practice exams leave old questions by mistake. Others do so on purpose in case Oracle hasn't removed the topic from the exam.  This exam isn't new though so it isn't coming back.
