>You can append to a string. You can prepend to a string. You can reverse a string. And that's all API's are. There definitions of things you can do to a given structure. If the API was "Shazam.PowerBuilder.AwesomeThing()" I'd understand this position. But it wasn't. It was obvious lists of "facts" about given structures. But in Java I can't add to a string. I can't prefix a string. Nor can I invert a string. So the things you mention aren't mere definitions or facts about things you can do to a string. They're methods specifically chosen by the language designer to be useful and those choices are a big part of what makes Java different from Ruby, for example.
