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".

Java 7 introduced type inference changes regarding generic class instantiation and generic constructors.

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 ...
