Why is programming often taught with basics like ‘Hello World’ before delving deeper into concepts?

Hi everyone! I'm currently learning Java in my senior year of high school, having previously earned my Python certification a couple of years ago. I've recently noticed that when I try to tackle projects beyond what we've covered in class, I often hit a wall that makes me question my understanding of Java. For instance, I stumbled upon some code that creates a 'new Main' object, which was confusing since I've always viewed 'Main' merely as a container for the program's execution start point. Additionally, I realized I don't fully grasp what the '(String[] args)' part means in the main method.

This brings me to my question: Why are we taught the 'basics' of programming languages, like printing 'Hello World', before we explore deeper concepts like classes and their functions? There are some other instances where I'm taught specific functions without understanding their underlying mechanisms, like:

- Why printing text requires 'System.out.'
- Why I need to specify '(System.in)' when creating a Scanner object for text input.
- The reasoning behind catching errors with '(Exception e)'.
- How executing '.nextLine()' after inputting a number adjusts the Scanner for text input.

Thanks for any insights!

It's like learning to ride a bike. You learn the basics first—how to start it moving—before getting into the more complex mechanics. Programming is often taught in a depth-first fashion because educators want you to gain practical skills quickly. But that means you'll have to bridge the gap yourself at times, diving deeper into aspects like error handling and the underlying structure of the language after you've got some experience under your belt. No worries; this journey is part of mastering programming!

Honestly, breaking concepts down to a 'Hello World' makes sense for most people. They want to see instant results rather than getting bogged down in theory. You learn the foundations first—like how to print something—before tackling more complex topics like class structures. It's like driving a car; you don't need to know how the engine works before you can drive it. If you want to know the deeper meaning of something, Google is your friend!

You're right; many courses are structured this way. Intro programming classes usually cover the basics like data types and loops, but they may not always emphasize the underlying mechanics of the language itself at first. That's why you see a disconnect; the courses tend to give you the tools to start coding, but the specifics often get glossed over. So in a sense, your experience with Java could seem more complicated than easier languages like Python, which tend to focus more on simplicity for beginners. But stick with it, you'll get there!

It's great that you're diving into programming! What you're experiencing is pretty common in many programming courses. Often, the focus in introductory classes is on getting you to write code and see results quickly. This approach might skip over deeper explanations about how the language works and instead cover the basics to get you familiar with variables, types, loops, and eventually classes and objects. Essentially, you're learning how to code, not just how to use Java specifically. It's about building your coding skills in a general sense before zeroing in on the particulars of the language.

Your observations are spot on! Java has a reputation for being somewhat verbose compared to languages like Python or JavaScript, which can be more beginner-friendly. The first programming courses often introduce coding fundamentals by using Java's syntax without diving deep into its object-oriented nature until later courses. This means you might feel overwhelmed by Java's requirements before you even get to solidify your understanding of how it all connects. A practical tip? Build small projects and work backward; it helps clarify what you need to learn as you go!
