So making this conversion who is gonna call this method might not notice it until the exception happens.
Just like the cast operator, the instanceof operator is also used only sparingly in professionally written code. Usage of instanceof reflects a bad design and if you feel the need to use instanceof operator in your code too often, you should think about redesigning your application.

Lots of demand for Java developers. I did a lot of Java development during grad school, but I've definitely fallen out of practice. Certification seems like an attractive option for me. I know the Java 11 certifications are out, but from what I have read they are significantly more difficult than the Java 8 OCA exam. Would it be worth getting a OCA certification in Java 8, or is that considered a waste of time, and just go for Java 11?
Akshay Kamat wrote:Hello,
This is my first post in the forum. I have recently started studying the OCA Java SE 8 Programmer I Study Guide by Jeanne and Scott. I have a fair amount of knowledge in Java and want to schedule the OCA exam. However, I'm confused with when should I schedule it with respect to me completing studying the entire book.

I bought the mock exams for Java 8 and I'm scoring about 80ish.

Given that my current company is still rolling out Java 8, I assume that studying the books that I already purchased and obtaining both the OCA and OCP Java SE 8 certifications is the best path forward for me.
