BufferedReaderClass in Java(I/O Stream)

BufferedReaderClass in Java(I/O Stream)

Using java BufferedReader class we can to read input from either keyboard or existing file.This BufferedReader class is used to read the character from charecter input stream.

There are three input stream in java (IO stream)

System.in,System.out,system.err

InputStreamReader → read bytes and decoded to charecter set

File Reader —> used to read data from existing file

This is  done with the help of  system.in(standard I/Ostream)

The buffered data is read using the BufferedReader class method

Each class has many methods.To invoke this method

object must be created.When reading data using filereader class,

if the file does not exist, an exception is raised.So when using the

bufferedreader class, the program should include IOException

BufferedReader class available in io package.If you want to

implement methods in the BufferedReader class, you have to import io package

Methods available in bufferedreader class

Reads charecter/string

read()--->read single charecter

readLine()--->reads multiple charecter or string

How to implement this method

InputStreamReader ir=new InputStreamReader(System.in);  

BufferedReader br=new BufferedReader(ir);

String str=br.readLine();
