JumpStart to Java 11 Programming for Object Oriented Experienced Developers

Course Objectives

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
• Understand and use classes, inheritance and polymorphism
• Understand and use collections, generics, autoboxing, and enumerations
• Abstract, static and private methods in interfaces
• Use Collections and Streams
• Take advantage of the Java tooling that is available with the programming environment being used in the class

Need different skills or topics?  If your team requires different topics or tools, additional skills or custom approach, this course may be further adjusted to accommodate.  We offer additional Java and JEE programming, design, testing and application security courses which may be blended with this course for a track that best suits your development objectives. Our team will collaborate with you to understand your needs and will target the course to focus on your specific learning objectives and goals.

Course Prerequisites

This is an introductory-level Java programming course, designed for experienced developers who wish to get up and running with Java, or who need to reinforce sound Java coding practices, immediately.  Attendees should have a working knowledge of developing OO software applications (coming from C++, C# or other OO programming backgrounds)..
