Groovy Goodness: Uncapitalize Strings

Since Groovy 2.4.8 we can use the uncapitalize method on CharSequence objects. The capitalize method was already available for a long time, but now we have the opposite as well.

In the following example we see that the uncapitalize method only replaces the first letter of a String value to lower case:

assert 'Groovy'.uncapitalize() == 'groovy'
assert 'MrHaki'.uncapitalize() == 'mrHaki'

String message = 'Groovy Rocks!'
assert message.uncapitalize() == 'groovy Rocks!'

Written with Groovy 2.4.8.
