1.1 Introduction
Welcome to the CodeHS Computer Science A textbook! This textbook teaches the foundations of computer science and the Java programming language, with an emphasis on the AP Computer Science A curriculum.
At its essence, computer programming is simply a set of instructions that are written in a language that the computer can understand. These languages are called programming languages, and they are very similar to our human languages like English, Spanish, and Chinese, though they focus on human-to-computer communication. Java is a common programming that is used around the world in schools and in industry.
That being said, many of our modern programming languages revolve around the same core components and ideas, and these are the topics in Java that you’ll be learning about in this textbook. This textbook is designed for students that may not have had any prior coding experience, but will also challenge experienced students.
With that, let’s dive in!
