OVERVIEW

Fast Track to Java Programming for Object Oriented Experienced Developers is a four-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.

This course includes several aspects that were introduced in Java 9, Java 10 and Java 11 including the Java Modular System, Local Variable Type Inference and several API updates. Developers leaving this course will be able to work on Java 8 projects while they are also ready to move onto projects using Java 11. This course also inlcudes a Quick Look at what’s next in Java – Java 12, Java13,, Java 14 and beyond.

GOALS

This “skills-centric” course is about 50% hands-on lab and 50% lecture, designed to train attendees in core OO coding and Java development skills, coupling the most current, effective techniques with the soundest industry practices. 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
  • Specific Java 11 features covered: Using the Local Variable Type in Lambda expressions; Updates made to the String API
