Codecademy's Learn Java course teaches Java syntax, object-oriented programming (classes, inheritance, polymorphism), and working with data structures like arrays and lists. The lessons are interactive: you write Java code in the browser with instant feedback. The free tier covers the basics; the full course including projects requires a Codecademy Pro subscription. After finishing the free tier, you understand Java fundamentals and can write simple programs. The main limitations: the free tier is only part of the course, the browser environment doesn't feel like real development, and Java is more verbose than languages like Python, so the learning curve is steeper.
Java is the third most-used programming language globally and powers nearly every enterprise backend system (source: Stack Overflow Developer Survey 2024).

Frequently Asked Questions
Is Codecademy's Java course free?
The first section is free. The full course with projects and exercises requires a Codecademy Pro subscription at around $19.99/month.
Is Java a good language to learn first?
Not ideal for absolute beginners. Python or JavaScript are gentler. Learn Java if you want to work in enterprise environments or Android development.
What are classes and objects?
In Java, a class is a template for objects. Most Java code revolves around creating classes and using them. It's the core of object-oriented programming.
Is learning Java in the browser the same as real development?
The concepts are the same, but real Java development uses an IDE like IntelliJ or Eclipse. After Codecademy, install JDK and an IDE to work on real projects.
What should I do after this?
Build a project on your local machine with an IDE. Object-oriented programming concepts matter more than Java specifically, so you can transition to C#, Python, or other OOP languages if Java feels too verbose.
