Subtyping in Java generics

Read Original

This technical article delves into subtyping within Java's generic type system. It explains why generic types of the same class (e.g., List<Number> and List<Integer>) do not form a subtype hierarchy, using examples to illustrate type safety and the prevention of ClassCastExceptions. The discussion includes the role of types in adding redundancy and safety to programs.
