Working with Roman Numerals
Problem
You need to format numbers as Roman numerals. Perhaps you've just written the next
Titan-
ic
or
Star Wars
episode and you need to get the copyright date correct on the script. Or, on a
more mundane level, you need to format page numbers in the front matter of a book.
Solution
Use my
RomanNumberFormat
class:
RomanNumberFormat nf
=
new
new
RomanNumberFormat
();
int
int
year
=
LocalDate
.
now
().
getYear
();
System
.
out
.
println
(
year
+
" -> "
+
nf
.
format
(
year
));
Running
RomanNumberSimple
produces this output:
2014 -> MMXIV
