This course focuses exclusively on teaching Java to beginners and demystifies procedural programming by grounding each concept in a hands-on project. 

You’ll start by learning built-in input and output methods, followed by user-defined methods. As you progress, you'll explore basic data types and apply them in sequential, selective, and iterative program structures. 

Finally, you'll use these concepts to complete an engaging project. By the end, you'll develop a fascination with Java programming, making it an excellent start to a career in computing for anyone looking to learn Java.
