I concede that this is how things are done in Java, and C# even suggests adding an extra level of depth for good measure with its namespaces, so maybe there's some prize for hitting the tab key a lot that no one told me about. Regardless, if you have ever worked someplace (like ...
Because Duke is a JavaMascot, we can change the return type when overriding.Polymorphism with the core Java classesWe use polymorphism all the time in the core Java classes. One very simple example is when we instantiate the ArrayList class declaring the List interface as a type:List<String>...
