JumpStart Your Java 11 Skills with Latest Features & Best Practices for Building Robust Applications

TT2104-J11

Introductory

4 Days

Course Overview

If you're an experienced OO developer (coming from a C# or C++ background, etc.) who needs to transition to programming in Java, this fast-paced, hands-on course will get you there quickly. Fast Track to Java Programming for OO Experienced Developers is a four-day, lab-intensive class where you'll quickly be immersed in working with the latest Java 11 programming techniques, using best practices for writing solid, robust (and well-written!) modern object-oriented applications. In addition to learning excellent, current coding skills in Java, you'll explore the new improved features for better performance and new capabilities for addressing rapid application development that Java 11 brings to the table. This course includes several key 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.  This course also includes a Quick Look at what’s next in Java’s latest editions.

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
  • Time Permitting: Quick look ahead – What's New in the Latest Java Editions

NOTE: This course is for the Java 11 LTS (Long-Term Support) edition, but is also available for Java 8 LTS or Java 17 LTS. This course also uses the Eclipse IDE, but is also available for IntelliJ if preferred. Please inquire for details.
