Question

I see no real difference between the following two methods of creating a setter, but was wondering if I am just naive. Is one more desirable than the other?

public void fooSetter(String bar)
{
    _bar = bar;
}


public void fooSetter(String bar)
{
    this._bar = bar;
}

Answer 1

There is no semantic difference in this case because there is no ambiguity. If, on the other hand, your instance field was also called bar then this would be required to disambiguate:

public void fooSetter(String bar)
{
    this.bar = bar;
}
