Working within in an engaging, hands-on learning environment, guided by our expert team, attendees will learn to:

• Understand not only the fundamentals of the Java language, but also its importance, uses, strengths and weaknesses
• Understand the basics of the Java language and how it relates to OO programming and the Object Model
• Learn to use Java exception handling features
• Work with the Java 9 modular system (Project Jigsaw)
• Understand and use classes, inheritance and polymorphism
• Understand and use collections, generics, autoboxing, and enumerations
• Process large amount of data using Lambda expressions and the Stream API

Specific Java 9 features that are covered in the course include:

• The Modular system (Project Jigsaw)
• Private methods in interfaces

Attendees should have a working knowledge of developing OO software applications.

This is an introductory- level Java course, designed for experienced developers who wish to get up and running with Java, or who need to reinforce sound Java coding practices, immediately.
