TT2000 - Java for Non-Developers | Getting Started with Programming, OO, and Java Basics

Getting Started with Programming, OO and Java Basics for Non-Developers is a fast-paced, five day course designed to provide you with a first look at how to code in Java to a very basic level. You’ll gain light hands-on programming experience, while you begin your journey to develop a programmer’s mindset.

Throughout the course you’ll explore the intricacies of the application development cycle, program structure, and language syntax. You’ll learn and practice core coding skills including fundamental OO concepts, vital programming constructs, string and character manipulation, dynamic memory allocation, standard input/output, and exception handling. You’ll also explore the power of inheritance and polymorphism as you learn to define specialized object implementations. The course also covers processing command line arguments and environment variables, empowering you to set up your own development environment to create flexible, user-friendly programs. With a wealth of hands-on lab exercises, you’ll practice and refine your newly acquired skills.

Becoming a modern software developer is like learning a new language; it requires study, practice, and dedication well beyond this course to apply your new skills effectively. While this five day program won’t transform you into an experienced developer, it will lay a solid foundation in coding basics using Java, while teaching you to think like a programmer. Although this course is technical in nature, our instructors will guide you every step of the way, providing a supportive environment for you to explore, ask questions, and prepare for your next learning milestones.

NOTE: Although this course is geared for non-developers, it is helpful for attendees to have a somewhat technical background and to be comfortable working with computers, having the ultimate goal of becoming a Java software developer.
