You can also implement theJava Iterableinterface using Java generics. Doing so is explained here: Java Generics Wildcards The Java generics wildcards enable you to specify not just a specific generic type for a class or collection, but that the required type could also be either a superclass ...

Instances of classes that implement this interface must implement an equals() method that equates any two instances that share the same generic type declaration and have equal type parameters. Added in 1.5. Java documentation for java.lang.reflect.ParameterizedType.Portions...
