Java Fundamentals

In this lesson, we'll cover some fundamentals—such as why you would want to learn Java, and what prerequisites you'll need to succeed in the course.

This lesson covers all the major building blocks we need to create a simple Java app, including keywords, variables, loops, methods, access modifiers, arrays, and Javadoc.

In this lesson, we'll learn about what an object is, what a class is, and how we can create (or instantiate) objects from classes.

In this lesson, we'll go deeper into objects and classes and learn about some of the advanced concepts of object-oriented programming, including inheritance and polymorphism.

We'll learn about some of the important class types provided by the Java API, including Exceptions, Enums, RegEx, Dates and Calendar, and advanced String features.

Working with multiple types can introduce some challenges. In this lesson we'll learn how two tools—generics and collections—can help us address these challenges and make our code type safe.

In this lesson we'll learn about maps, sets and queues. Each of these provides a uniquely powerful data structure that, when used correctly, can solve complex problems efficiently.
