AP Computer Science teaches high school students the fundamentals of coding and programming through analyzing problems, developing algorithms, and writing code. But what language do students use to implement their solutions?
In this comprehensive guide, we’ll explore the AP computer science courses, the languages used, and the reasoning behind these choices.
Overview of AP Computer Science Courses
Computer Science A
The AP Computer Science A course is designed to introduce students to the fundamental concepts of computer science and programming. It covers topics such as problem-solving, algorithms, data structures, and object-oriented programming using the Java programming language.
This course requires a strong foundation in mathematics and logical thinking. Students will learn how to write and analyze code, develop algorithms, and solve complex problems. The curriculum is rigorous, and students are expected to have a solid understanding of programming concepts by the end of the course.
Computer Science Principles
The AP Computer Science Principles course is a more broad-based introduction to computer science. It focuses on the big ideas of computing, such as creativity, abstraction, data and information, algorithms, programming, the internet, and the global impact of computing.
The course aims to provide students with a comprehensive understanding of the principles and practices that underlie the study of computer science. Unlike Computer Science A, this course does not require prior programming experience.
It is designed to be accessible to students from various backgrounds and interests.
Objectives and Focus of Each Course
Computer Science A is more focused on programming and problem-solving skills using the Java programming language. It aims to provide students with a deeper understanding of programming concepts and prepare them for further study or careers in computer science.
On the other hand, Computer Science Principles covers a broader range of topics, including the societal and ethical implications of computing. It aims to develop computational thinking skills and an understanding of how computer science impacts various aspects of our lives.
Both courses are part of the College Board’s Advanced Placement (AP) program, which allows students to earn college credit or advanced placement in college courses. The exams for these courses are rigorous and require students to demonstrate their knowledge and skills in computer science.

Use of Java in Computer Science A
Java is the primary programming language used in the College Board’s AP Computer Science A course. It is a widely-used, general-purpose language that has become the de facto standard for many computer science programs and industry applications.
Widely-used, general purpose language
Java’s popularity stems from its versatility and ease of use. It is a general-purpose language, meaning it can be used to develop a wide range of applications, from desktop software to mobile apps and web applications.
Its syntax is similar to other popular programming languages, such as C++ and C#, making it relatively easy for students to transition to other languages if needed.
Object-oriented programming concepts
One of the key reasons Java is used in AP Computer Science A is because it is an object-oriented programming (OOP) language. OOP is a programming paradigm that allows for the creation of modular, reusable code by organizing data and behavior into objects.
This concept is fundamental to computer science and is widely used in industry. Java’s strong support for OOP makes it an ideal language for teaching these concepts.
Robust library of utilities
Java comes with a vast standard library that provides a wide range of pre-written code and utilities, making it easier for students to develop complex programs. The library includes functions for handling input and output, working with data structures, networking, and much more.
This comprehensive library saves time and effort by providing ready-made solutions to common programming tasks.
Developer and industry demand
Java is in high demand in the software development industry, with many companies seeking Java developers for a variety of roles. By teaching AP Computer Science A in Java, students are equipped with valuable skills that are relevant in the job market.
Additionally, the widespread use of Java in the industry means that students have access to a wealth of resources, online communities, and open-source projects to further enhance their learning.
Java is designed to be platform-independent, meaning that programs written in Java can run on different operating systems without modification. This makes it a versatile language that can be used to develop applications for Windows, macOS, Linux, and even mobile platforms like Android.
The ability to write once and run anywhere makes Java an attractive choice for developers and an ideal language for teaching computer science concepts.
Scratch, Snap!, App Lab
When it comes to the AP Computer Science Principles course, students have the opportunity to explore various programming languages. One popular choice is Scratch, a visual programming language developed by MIT.
Scratch allows students to create interactive stories, games, and animations by simply dragging and dropping blocks of code. It’s a great way to introduce beginners to the world of coding and help them understand programming concepts in a fun and engaging manner.
Another visual language that is commonly used in CS Principles is Snap!. Similar to Scratch, Snap! provides a block-based interface that allows students to create their own programs. It offers more advanced features and is often used to teach more complex programming concepts.
Abstract thinking without syntax challenges
One of the advantages of using visual programming languages like Scratch and Snap! in the CS Principles course is that it allows students to focus on abstract thinking and problem-solving without getting caught up in the complexities of syntax.
This means that students can start coding and experimenting with ideas right away, without having to worry about making syntax errors. It removes one of the barriers that often intimidates beginners and allows them to develop their computational thinking skills in a more accessible way.
Visual programming languages also enable rapid prototyping, which is crucial in the field of computer science. With tools like Scratch and Snap!, students can quickly create and test their ideas, iterate on them, and see the results in real-time.
This iterative process helps students refine their designs and solutions, fostering a mindset of continuous improvement and innovation.
Benefits of These Languages for New Coders
Gentle learning curve
One of the key benefits of using the languages in AP Computer Science is their gentle learning curve. These languages, such as Java and Python, are known for their simplicity and ease of understanding. This makes them ideal for beginners who are just starting their coding journey.
With clear syntax and straightforward concepts, new coders can quickly grasp the basics and build their programming skills from there. It’s like learning a new language that is designed to be beginner-friendly.
Readability and plain English commands
Another advantage of using these languages is their readability and plain English commands. Unlike some programming languages that can be difficult to understand due to their complex syntax, Java and Python prioritize human readability.
Their commands are designed to resemble everyday English language, making it easier for new coders to understand and write code. This not only enhances the learning experience but also encourages better collaboration among programmers working on the same project.
Java, which is one of the languages used in AP Computer Science, offers the benefit of cross-platform portability. This means that Java code can run on different operating systems without the need for major modifications.
Whether you’re coding on a Windows, Mac, or Linux machine, Java allows you to develop applications that can be used on multiple platforms. This versatility is highly valuable in today’s interconnected world, where a single application may need to work seamlessly across various devices and operating systems.
Vibrant developer community and resources
Both Java and Python have vibrant developer communities that offer a wealth of resources for new coders. Online forums, discussion groups, and websites dedicated to these languages provide a supportive environment where beginners can seek help, share ideas, and learn from experienced programmers.
Additionally, there are numerous tutorials, documentation, and open-source projects available, allowing new coders to explore and gain hands-on experience. Being part of a thriving community not only helps in overcoming challenges but also fosters networking and career opportunities for aspiring programmers.
