Course Overview
The Java Programming 2 course is closely aligned with the Oracle Java SE 8 Programmer II exam.
This 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 8 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.
The most important new topics introduced in Java SE 8 are covered, such as Functional Programming and Stream API, that allow you to use the most up to date techniques in your code.
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
Who will the course benefit?
The Java Programming 2 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.

Entry Requirements
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 course.
Pre-requisite Courses
• Java Programming 1
Follow-on Courses
• Java Web Services
• Developing Applications with Java EE
• Unit Testing using JUnit
• Core Spring
Notes
• Course technical content is subject to change without notice.
• Course content is structured as sessions, this does not strictly map to course timings. Concepts, content and practicals often span sessions.
Exam
There is no exam requirement for this course.
The Java Programming 2 course helps delegates prepare for the following exam:
Oracle Certified Professional (OCP) Java SE8 Programmer II exam (1Z0-809)
Attending this course will help delegates gain many of the skills and product knowledge requirements as outlined in the exam objectives. Studying this course and its 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.
Course Objectives
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.
The course further aims to prepare the delegate to sit the Oracle Java SE 8 Programmer II exam.

Chris |Gov.uk –
Instructor managed to assess the skill level of the classroom and adjust the delivered material in a way the benefited us the most. Perfectly pitched.
Barbara | Engineer in Test –
It’s the most useful experience in my all education process (and I’m saying this after PhD in Physics). All the knowledge served in amazing form with humour. Thank you!
