“Learn Object-Oriented Java the Hard Way” focuses on the object-oriented parts of Java and covers them deeply, with plenty of complete working examples and the explanations you won’t find in other books.

You need some experience Java or a similar language before you will be able to make it through this material. If you have never programmed before in any language, you should start with my intro book “Learn Java the Hard Way”. But if you already know the basics of Java or another language like C, C++, C# or Javascript, this book is for you. And if you only know a very different language like Python or Ruby then you will have some catching up to do but will probably still be fine.

In the final chapter you’ll write a graphical version of a popular checker-dropping game and know how to package it up in a JAR file to send to others.

You will learn:

How to install the Java compiler and a text editor
How to work with Java objects and create your own classes
Fields and instance variables
Methods and Parameters
Constructors
Reference Variables vs Primitives
Generics and Casting
Inheritance
Interfaces
Abstract Classes and Methods
Packages
How to create JAR files
Graphical User Interfaces in JavaFX
Mouse and Keyboard Input in GUIs
Testing and Efficiency
Algorithmic Complexity and Big-O Notation
ArrayLists
Sorting

...and more!
