Java Programming 2 / Java Advanced Developer

The Java Programming 2 / Java Advanced Developer course focuses on the core language features and Application Programming Interfaces (APIs) you will use to design effective object-oriented and functional programming applications with the Java Standard Edition 11 Platform.

The delegate will learn how to design and develop robust Java code that is easy to test and maintain and can be integrated into multiple applications.

Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.

The delegate will learn and acquire skills as follows:

• Implementing code using inheritance and polymorphism
• Using design patterns to ensure robust design of classes
• Overriding key methods of the Object class to provide interoperability with collections and other APIs
• Understanding and using Generics within existing classes and create new Generic classes
• Creating and using collections including sets, maps and queues
• Selecting and incorporating standard functional interfaces in code
• Using Stream API to generate, filter, process and reduce stream data
• Writing Lambda expressions for use within code including with functional interfaces
• Declaring try-with-resources blocks and using AutoCloseable classes
• Working with Java SE8 Date/Time API classes
• Reading and writing data from/to the Console
• Managing files and directories
• Writing concurrent code and using Concurrent API
• Using parallel streams
• Building database applications with JDBC

The Java Programming 2 / Java Advanced Developer course is aimed at staff and consultants working as part of a Java development team to develop high-quality robust software. Roles include Programmers, Designers, Architects, Testers and anyone who needs a good understanding of the use of the Java language and infrastructure.

This course aims to provide the delegate with the knowledge to be able to produce robust, scalable, and testable Java code that may be integrated into enterprise applications and that go beyond the core elements of the language exploiting design patterns, functional programming, collections, date and time, input/output, concurrency and JDBC.

This Java Advanced Developer course helps to prepare for the following exam:

• Oracle Certified Professional (OCP) Java SE 8 Programmer II: 1Z0-809

This course together with the Java Programming 1 / Java Developer course helps to prepare for the following exam:

• Oracle Certified Professional (OCP) Java SE 11 Developer: 1Z0-819

Attending this course will help delegates gain many of the skills and product knowledge requirements as outlined in the exams objectives. Studying these courses and their associated reference materials can form part of the preparation to achieve certification. Experience, practice, self-study and aptitude are also key requirements for exam success.

Before taking any exam, ensure you have the recommended experience. The Oracle website lists all exam requirements and these are updated regularly.

Exams are not included as part of the course.

Delegates attending this course should have experience programming with an object-oriented language, ideally Java. This knowledge can be obtained by attendance on the pre-requisite Java Programming 1 / Java Developer course.
