SE450: Overriding: Overriding [10/35]

Overriding: a non-static method in a subclass has the same name and signature as a non-static method in the superclass.

Intuition: the method implementation in the subclass ``replaces'' the implementation of the method in the superclass.

Example:

class B {
  public void m() { ... }
}
class D extends B {
  public void m() { ... }
}
B b = new B(); b.m(); // invoke m in class B
D d = new D(); d.m(); // invoke m in class D
