Oracle comunica que el periodo Beta del examen ha finalizado, realizando las publicaciones de resultados en CertView aproximadamente el 26 de Enero de 2015.

Esto supone que el examen pasa a fase de producción. Es decir, cualquier persona puede registrarse y solicitar cita para el examen previo pago en PersonVue.

Como es lógico, desde el punto de vista empresarial, Oracle cuenta con una gran ventaja didáctica en este sentido, lo que le permite sugerir, que, para aprobar el examen, la mejor manera de hacerlo es mediante el curso Java SE 8 Fundamentals, curso online, con un precio de 2400 dólares, y duración de 5 días.

Alternativamente, vemos documentación oficial de java 8 en:

http://docs.oracle.com/javase/8/docs/api/

Y de, a mi parecer, la autora más brillante en esta materia (Kathy Sierra) vemos que, de momento, sólo ha llegado a publicar información sobre la ocjp hasta la versión 7.

Por cierto, me ha chocado ver que Kathy Sierra abandonó la cuenta de twitter (según leí por encima por culpa de trolls) y por otro lado, veo dos de sus blogs relativamente desactualizados (en una primera instancia).

Differentiate between object reference variables and primitive variables

Know how to read or write to object fields

Explain an Object's Lifecycle (creation, "dereference by reassignment" and garbage collection)

Working with Inheritance

Describe inheritance and its benefits

Develop code that demonstrates the use of polymorphism; including overriding and object type versus reference type

Determine when casting is necessary

Use abstract classes and interfaces

Handling Exceptions

Differentiate among checked exceptions, unchecked exceptions, and Errors
