You’ll start Java with the basics, such as printing messages, doing math, and working with user input, before exploring loops, conditionals, and object-oriented programming. Along the way, you’ll build real console apps, like games and menu systems, while learning how to structure your code using classes, methods, and objects. This course emphasizes hands-on learning and real-world modeling, making Java feel less intimidating and more intuitive. Whether you’re aiming to become an Android developer or backend engineer, or just want a solid foundation in programming, this course will help you write clean, structured code and confidently take your first step into software development. You need to know absolutely nothing about programming before your first lesson.
