The method's name is misleading, as the implementation may trim the components. It also duplicates the functionality of the `toComponentsString()`. I suggest splitting it into two methods: `DottedVersion trim(int componentLimit)` and `DottedVersion pad(int componentLimit)`.

If they want to get a string representation of exactly 3 version components they would call:

ver.trim(3).pad(3).toComponentsString();
