L5: Taking Input in Java using Scanner Class | Full Concept Explanation with Examples | CWC

💻 Welcome to Carrier With Code (CWC) In this video, we will learn how to take input from user in Java using Scanner Class. This is one of the most important topics for beginners in Java programming. If you want to build real-world Java programs, you must understand how to take user input properly. 🧩 What You’ll Learn in This Video ✔️ What is Scanner Class ✔️ Why we use Scanner in Java ✔️ How to import Scanner Class ✔️ Different input methods ✔️ Common mistakes & solutions ✔️ Example programs 💡 Scanner Class Methods 🔹 nextInt() → Integer input 🔹 nextFloat() → Float input 🔹 nextDouble() → Double input 🔹 next() → Single word input 🔹 nextLine() → Full line input 💻 Example Program import java.util.Scanner; class Demo { public static void main(String[] args) { Scanner sc = new Scanner(System.in); int roll; String name; double marks; System.out.println("Enter Roll Number:"); roll = sc.nextInt(); sc.nextLine(); // fix for nextLine issue System.out.println("Enter Name:"); name = sc.nextLine(); System.out.println("Enter Marks:"); marks = sc.nextDouble(); System.out.println("Roll: " + roll); System.out.println("Name: " + name); System.out.println("Marks: " + marks); } } ⚠️ Common Mistake (Very Important) 👉 nextLine() skip ho jata hai after nextInt() ✔️ Solution: Use sc.nextLine() before taking string input 🧠 Concepts Covered ✔️ Scanner Class ✔️ User Input in Java ✔️ Input Methods ✔️ Java Basics 🔑 SEO Keywords scanner class in java taking input in java java user input java scanner example learn java programming java tutorial for beginners carrier with code java 📚 Hashtags #JavaProgramming #LearnJava #JavaForBeginners #ScannerClass #JavaInput #CodingForBeginners #CarrierWithCode #carrierwithcode
