Java Programming 2

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.
This course will teach you 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.

Prerequisites

• • 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.

Target Audience for this Course

• • 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.

Skills Gained from this Training

• • 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
