86. How to Get User Input in Java: Scanner vs. BufferedReader vs. System.in

Ready to move beyond basic System.out.println and make your Java applications truly interactive? In this lecture, we crack the code on getting your program to listen to the user, allowing you to build everything from simple calculators to text-based adventure games.
We break down the three distinct methods for handling user input in Java, exploring the pros, cons, and best use cases for each:
• The Basic Method (System.in): We start at square one with System.in.read. We explain why this "pipeline" approach often trips up beginners by reading single characters as ASCII integers rather than the text you expect.
• The Power Tool (BufferedReader): We analyze the classic, robust approach used by developers for years. Learn how wrapping InputStreamReader in a BufferedReader improves efficiency for reading whole lines, despite its complex setup.
• The Modern Solution (Scanner Class): Meet the undisputed champion for day-to-day coding. We show you how the Scanner class simplifies the entire process with easy methods like nextInt and nextLine, removing the need for manual parsing.
Finally, we wrap up with a "Final Showdown" comparison table to help you decide exactly which tool to use for your next project.
