Java 9 (or 10) and OO Programming Essentials for Developers New to OO is a five-day, hands-on Java training course geared for developers who have little or no prior working knowledge of object-oriented programming languages (such as those working on (C, COBOL, 4GL, etc.) Throughout the course, students learn the best practices for writing great object-oriented programs in Java, using sound development techniques, new improved features for better performance, and new capabilities for addressing rapid application development. Special emphasis is placed on object oriented concepts and best practices.

  • This course introduces new features in Java 9 and Java 10, including the Java Modular System and Local Variable Type Inference. Developers leaving this course will be able to participate in projects that are still on Java 8, while they are also ready to move onto projects using Java 10.

Skills Gained

Our engaging instructors and mentors are highly-experienced practitioners who bring years of current "on-the-job" application development experience into every classroom. Working within in an engaging, hands-on learning environment, guided by our expert team, attendees will learn to:

  • Understand what OO programming is and what the advantages of OO are in today's world
  • Work with objects, classes, and OO implementations
  • Understand the basic concepts of OO such as encapsulation, inheritance, polymorphism, and abstraction
  • 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
  • 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
  • Use the JDBC API for database access
  • Take advantage of the Java tooling that is available with the programming environment being used in the class

Who Can Benefit

This is an introductory -level course designed for attendees with prior development experience in another language, such as COBOL, 4GL, Mainframe or other non-object oriented languages. This course is not geared for non-developers.

Awesome instructor with in-depth knowledge and the ability to present in a meaningful & understandable way. This course will provide a solid foundation within DataStage that can be used immediately. I highly recommend this course.

Presentation and labs were thorough and detailed enough to get a broad understanding of AWS services.

well organized and designed course. Tommy is good teacher and answer our all the questions

Class had good pace, the curriculum appeared to focus on exam prep (which was good), the lab worked very well except for one small instance.

Great Class that will help as the state moves forward with the Cloud solution.
