Casting between interface sublass and superclass when superclass is not implementing interface but subclass is
casting, inheritance, interface, java
Solution
The compiler only checks if there is a possible relationship, and there is one:
A `LandMover` could be a `Car`, which in turn IS-A `Vehicle`. Since you promise that this conversion is ok by using an explicit cast, the compiler is happy.
Problem
In the following code ``` abstract class Vehicle { } class Car extends Vehicle implements LandMover { } interface LandMover { } Car porsche=new Car(); LandMover lmv; lmv = porsche; Vehicle vec = (Vehicle)lmv; ``` Shouldnt there be a compiler error in 4th line as there is no relation between class vehicle and Interface LandMover?? and if there isnt what could be the reason.Thanks!!
