Course Lessons

Lesson 1

Introduction to Java

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.

Lesson 2

Java Programing Basics

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.

Lesson 3

Defining Classes

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.

Lesson 4

Object-Oriented Programming

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.

Lesson 5

Common Types

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.

Lesson 6

Generics and Collections

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.

Lesson 7

Advanced Collections

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.

Lesson 8

Choosing the Right Collection

Lesson 9 • Project

Hotel Reservation Application

In this project, you will demonstrate your new Java skills by creating a fully functional hotel reservation app that will allow customers to check room availability and book a room.
