HOW TO TAKE INPUT FROM USER IN JAVA (USING BUFFERED READER CLASS) смотреть онлайн

INSTAGRAM | https://www.instagram.com/javac_programming/
This is the Java classical method to take input, Introduced in JDK1.0. This method is used by wrapping the System.in (standard input stream) in an InputStreamReader which is wrapped in a BufferedReader, we can read input from the user in the command line.

The input is buffered for efficient reading.
The wrapping code is hard to remember.

// Java program to demonstrate BufferedReader
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class Test {
public static void main(String[] args)
throws IOException
{
// Enter data using BufferReader
BufferedReader reader = new BufferedReader(
new InputStreamReader(System.in));

// Reading data using readLine
String name = reader.readLine();

// Printing the read line
System.out.println(name);
}
}
To read other types, we use functions like Integer.parseInt(), Double.parseDouble(). To read multiple values, we use split().
