Figure 16-6 shows an example of running the program. To start the program in a different
locale, you can set the
user.language
and
user.country
settings from the command line with a
command similar to the following:
java -Duser.language=fr -Duser.country=FR DateInputSample
However, this will alter the valid input only for those formats without a specific locale set.
