Subject: Continued a bit:
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=43544a1730a5019399f17f7a8ff596e581f75d5d;p=jcontacts-core.git

Continued a bit:
- if a mobile provider instance is given, but no number, throw an NPE before the JVM detects the null reference
- this may look like redundant but it makes the code more clear (and may become handy for unit tests)
- renamed cellphone -> mobile
