Core Java

Code and run your first Java program in minutes without installing anything! This course is designed for learners with limited coding experience, building on a solid foundation of Java. You’ll dive into key Java classes, interfaces, and frameworks, developing best practices, handling data, and connecting to web-based systems.

The modules in this course cover developer best practices, data handling, and connecting to web-based systems. Completion of an introductory Java sequence such as Codio's Hands-On Java Introduction is recommended. To allow for a truly hands-on, self-paced learning experience, this course is video-free. Assignments contain short explanations with images and runnable code examples with suggested edits to explore code examples further, building a deeper understanding by doing. You'll benefit from instant feedback from a variety of assessment items along the way, gently progressing from quick understanding checks (multiple choice, fill in the blank, and un-scrambling code blocks) to small, approachable coding exercises that take minutes instead of hours.

• Learners will develop best practices including following a code style guide, architecting code bases into projects, and unit testing.
• Learners will be able to handle data with Java's Collections framework, Streams (including the use of lambdas), and DateTime classes.
• Learners will connect to web-based systems, handle the errors that occur in the process, and parse responses into useful formats.
