Learn Java Programming _ Beginner to intermediate Level

Loony Corn
Filmed by


A Java course for everyone - accessible yet serious, to take you from absolute beginner to an early intermediate level. This course will use Java and an Integrated Development Environment (IDE). Never fear, we have a detailed video on how to get this downloaded and set up. This is a Java course for everyone. Whether you are a complete beginner (a liberal arts major, an accountant, doctor, lawyer) or an engineer with some programming experience but looking to learn Java - this course is right for you. Even so, this is a serious Java programming class - the gradient is quite steep, and you will go from absolute beginner to an early intermediate level.

Is this course for me?

Yep! Folks with zero programming experience - liberal arts majors, doctors, accountants, lawyers. Yep! Engineering students from non-CS majors looking to learn fairly serious programming. Nope! Experienced Java programmers - this class will be boring for you. Yep! Computer Science students or software engineers with no experience in Java, but experience in Python, C++ or even C#. You might need to skip over some bits, but in general the class will still have new learning to offer you.

What will I gain from this course?

Programming Basics: What programming is, and a carefully thought-through tour of the basics of any programming. Installing and setting up an IDE and writing your first program. The Object-Oriented Paradigm: Classes, Objects, Interfaces, Inheritance; how an OO mindset differs from a functional or imperative programming mindset; the mechanics of OO - access modifiers, dynamic dispatch, abstract base classes v interfaces. The underlying principles of OO: encapsulation, abstraction, polymorphism. Threading and Concurrency: A deep and thorough study of both old and new ways of doing threading in Java: Runnables, Callables, Threads, processes, Futures, Executors. Reflection, Annotations: The how, what and why - also the good and bad.

How do I prepare before taking this course? Is there a prerequisite skill set?

No prior programming experience needed. The class will make use of Java and an IDE - never fear, we have a detailed video to walk you through the process of setting this up.
