Take your coding to the next level by learning advanced programming with generics. Here's how to use generic methods with type inference, type parameters, and wildcards in your Java programs.

Java generic classes are compiled into bytecodes, assuming java.lang.Object for all type parameters (or, alternatively, a more specific class constraint). This is known as "type erasure".

The Java compiler includes a type inference algorithm that examines each generic method invocation and corresponding declaration to figure out the invocation’s type argument (s).

Generics not only let you create more flexible classes, they make inheritance more flexible, also. To pick the right inheritance mode when inheriting from a generic, though, you must know what you're ...

Ah, but my Entity is parametrized by the type of its leaf inheriting child, not some third type.<BR><BR>Extending his reasoning, I would have this:<BR><BR>class Entity<E extends Entity<E ...
