Java for Beginners Tutorial - Java Certification in 6.5 hours! Java 8 OCA (1Z0-808) Complete Course смотреть онлайн

This course starts with the very basics and continues right up to Java 8 OCA Certification. Many consider Java 8 OCA to be the baseline certification. In the course, many of the critical concepts in Java are explained in detail - for example: Scope, String Immutability, Encapsulation, Inheritance, Polymorphism, Designing Immutable Classes, Call-by-Value, Objects versus References, Interfaces, Enumerations, Exceptions, Lambdas and much, much more. The approach is systematic and detailed. There are plenty of code examples throughout.
Certification requires a different mindset. You do not have the help of a compiler in the Certification exams. Thus, you really have to understand the code i.e. what is happening 'under-the-hood'. This course presents from that viewpoint. A simple look at all the bookmarks reveals the detail.
