Introduction to Java 9 (UT-Java-9I)

Course Description

This is a five-day, comprehensive, and hands-on 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.

Course Objectives

Students who attend Java 9 and OO Essentials will leave this course armed with the required skills to develop solid object-oriented applications written in Java, using sound coding techniques and best coding practices. Geared for developers with prior OO development experience in languages such as C#, C++ or SmallTalk, this course will teach students everything they need to become productive in essential Java programming. 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 Java 9 modular system (Project Jigsaw)
• Learn to use Java exception handling features
• 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
• 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
• Specific Java 9 features that are covered in the course include:
• The Modular system (Project Jigsaw)
• Private methods in interfaces
