Introduction to Java 11 / 13 Programming for Object Oriented Experienced Developers is a five-day, comprehensive, hands-on introduction to Java training course geared for developers who have prior working knowledge of object-oriented programming languages such as C# or C++. Throughout the course, students learn the best practices for writing great object-oriented programs in Java 11, using sound development techniques, new improved features for better performance and new capabilities for addressing rapid application development.

Skills Gained

Our engaging instructors and mentors are highly experienced practitioners who bring years of current "on-the-job" experience into every classroom. Working in a 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 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
  • Abstract, static and private methods in interfaces
  • Take advantage of the Java tooling that is available with the programming environment being used in the class
  • Discover the use of enterprise APIs live CDI and JPA

Who Can Benefit

Experienced programmers with practical, current development experience in another OO language such as C++ or C#

Prerequisites

This is an introductory- level Java programming course, designed for experienced developers who wish to get up and running with Java, or who need to reinforce sound Java coding practices, immediately. Attendees should have a working knowledge of developing OO software applications.
