Buffered Reader is just like Scanner... BUT, Buffered Reader throws exceptions which makes it unworthy. Whenever we declare Buffered Reader, we also have to declare a statement for IOException. Thus, we prefer Scanned over Buffered Reader. For example, import java.io.*; public class CalcArea { public static void main ( String args[] ) throws IOException { System.out.print ( "Enter the radius: " ); BufferedReader input = new BufferedReader ( new InputStreamReader ( System.in ) ); String inputString = input.readLine(); double radius = Double.parseDouble ( inputString ); double area = 3.14159 * radius * radius; System.out.println ( "Area is: " + area ); } } Hope it helped... If liked plz follow me😅😉

Mayank Rampuriya... Stringing inputstring=input.readLine() basically reads the keys from the keyboard as a buffer....double radius=Double.parseDouble(inputString) converts what u entered from the keyboard to double data type...then the double data can be used in ur program....this is the basic explanation...that u can understand from above....readLine() is a function of BufferedReader class...
