Course Overview
Coming from C, COBOL or other Non-OO Language? Gain the Skills Needed to Start Writing Solid Object-Oriented Applications in Java.
Basic Java 11 and OO Prorgramming 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 10, 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 explores several items introduced in Java 9, Java 10 and Java 11 including the Java Modular System, Local Variable Type Inference, the HTTPClient API 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 includes a Quick Look at what’s next in Java – Java 12, Java13, Java 14 and beyond.
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.
NOTE: This course is offered for Java 8, Java 11 (for Java 9 to 11) LTS editions, or most current (12+). Please inquire for details.
What you’ll learn
- 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
- Take advantage of the Java tooling that is available with the programming environment being used in the class
- Java 11 features covered: Using the Local Variable Type in Lambda expressions; Updates made to the String API
Target audiences
- This is a basic-level programming 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. This course is for experienced developers with little to no prior OO development experience, such as C or COBOL programmers.
