How to take input through BufferedReader Class? Part-7
🎬 Introduction:
Hello everyone, welcome back to the channel. In today’s video, we are going to learn how to take input using the BufferedReader class in Java in a simple and clear way.
If you are a beginner in Java, a school or college student, or preparing for competitive programming, this topic is very important for you. BufferedReader is a faster and more efficient way to take input compared to Scanner, especially when handling large amounts of data.
In this tutorial, I will explain step-by-step how to create a BufferedReader object, how to read different types of inputs like String and Integer, and how to handle exceptions properly.
Step 1: Import the Package
import java.util.BufferedReader;
Step 2: Create BufferedReader Object
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
Step 3: Reading Different Types of Input
Reading a String
String name = input.readLine();
Reading an Integer
int age = Integer.parseInt(br.readLine());
Reading a Double
double salary = Double.parseDouble(br.readLine());
📌 Important Point:
-- readLine() throws IOException, so you must:
-- Use throws IOException
OR
-- Use try-catch block
📌 Why BufferedReader is Faster than Scanner?
-- BufferedReader reads data in large chunks (buffer)
-- Scanner parses input internally (which makes it slower)
-- Preferred in competitive programming
