Description

I recently came across a problem which I expected to be solved already by StringUtils or Word Utils.
Some input like "MY_TINY_PROPERTY" needed to be converted to a bean name "myTinyProperty".
The code I wrote for that (far from perfect) looks like this:

private String toCamelCase(String value, boolean startWithLowerCase) {
String[] strings = StringUtils.split(value.toLowerCase(), "_");
for (int i = startWithLowerCase ? 1 : 0; i < strings.length; i++)

{ strings[i] = StringUtils.capitalize(strings[i]); }

return StringUtils.join(strings);
}

The way back would be a bit more complicated.

If there is consensus that such a function could be useful, I am willing to create a patch. However I can see reasons for not creating such a functionality (especially with the way back) because requirements might differ. What is the commons approach here. Implement something for the 80% case?
