Core java question

Suppose we have three classes X, Y, and Z

1.X has a public method f()

2.Y extends X and overrides f()

3.Z extends Y

4.x is an object of type X, y is an object of type Y and

z is an object of type Z.

when I invoke z.f(), which version of f() will be called?

The one in Y, i.e. y.f() or x.f()?

I presume that it will be y.f(). Could anyone tell me why y.f() will be invoked. I need to know the concept behind this.

Appreciate a speedy reply for this.
