Does Overiding a Method Effect a Super Class's Call?

I'm trying to understand some of the nuances of inheritance but I can't find an answer to this question. Consider the following:

class SuperClass {
    method foo {
        print "in SuperClass.foo"
    }
    method bar {
        print "in SuperClass.bar"
        foo();
    }
}
class SubClass inherits SuperClass {
    method foo {
        print "in SubClass.foo"
    }
}

SubClass a = SubClass.new()
a.bar()

Is the output this:

in SuperClass.bar
in SuperClass.foo

Or this:

in SuperClass.bar
in SubClass.foo
