[Research] Visual Basic - The Object Class

There is a class called X that contains the following overridable methods:

Run()

Walk()

Hide()

There is a class Y that inherits from class X. Is Y able to override the Run, Walk & Hide methods in X?

Yes, Y can override the methods from class X, since X is the parent. X can call it's own functions even if Y overrides them, but Y if it overrides X's methods cannot access X's original methods only the newly written overriding one.
