Taking User Input in Java | Scanner Class vs BufferedReader | Lecture 4

Lecture 4: User Input, Scanner Class & The "Buffer Glitch" Explained In this video, we make our code "Interactive"! We stop hardcoding values and give our computer "Ears" to listen to the user. We go deep into the history of Input in Java—from the Caveman era (`System.in.read`) to the Strict Grandpa (`BufferedReader`) and finally the Modern Smartphone (`Scanner`). Most importantly, we fix the famous "Scanner Bug" where `nextLine()` gets skipped after `nextInt()` Topic Covered: 1. Evolution of Input: System.in.read() vs BufferedReader vs Scanner. 2. How to import and use the Scanner Class. 3. Taking Int, Float, String, and Boolean inputs. 4. The Buffer Issue: Why does Java skip the String input? 5. The Solution: Cleaning the Buffer.
