Question

What is the most elegant way to convert a hyphen separated word (e.g. \"do-some-stuff\") to the lower camel-case variation (e.g. \"doSomeStuff\") in Java?

Answer 1

As I'm not a big fan of adding a library just for one method, I implemented my own solution (from camel case to snake case):

public String toSnakeCase(String name) {
    StringBuilder buffer = new StringBuilder();
    for(int i = 0; i < name.length(); i++) {
        if(Character.isUpperCase(name.charAt(i))) {
            if(i > 0) {
                buffer.append('_');
            }
            buffer.append(Character.toLowerCase(name.charAt(i)));
        } else {
            buffer.append(name.charAt(i));
        }
    }
    return buffer.toString();
}

Needs to be adapted depending of the in / out cases.
