Methods on objects should be verbs or questions.
Sometimes it's appropriate that the verb is to set some state.
But generally no, the state of the object should not be visible or changeable from outside the object. So you don't need getters and setters.
If you find yourself with a "bag of values" object, just make it a verbless bag of objects. And make all the members public and save a bunch of typing.
One of the common flaws of developers is that given a setter interface, they try and drive the objects through it, leading to pages of boring settering code instead of a single verb operation to abstract that away -- and which, appropriately named, tells you what it does.
