Using "this" in Java vs Short Parameter Names

Question

Which do you prefer and why?

public void setPresenter(Presenter presenter) {
    this.presenter = presenter;
}

public void setPresenter(Presenter p) {
    presenter = p;
}

Answer 1

I prefer the this-notation, at least in constructors, and compound setter methods, where you have multiple arguments.

• You don't have to come up with two variable names for each field.
• It is clear from the "outside", what the argument represents.
• It is really a standard approach.

In the particular case of a setter, I don't really have an opinion, since the method name is explanatory enough, and the implementation is a single assignment.
