• A cast towards an object's ultimate super type - that is, `up' the inheritance hierarchy towards the Object class, for instance

   // Upcast from VariableController to HeaterController VariableController v; ... HeaterController c = v; 

  See downcast. Java's rules of polymorphism mean that an explicit upcast is not usually required.
