Reading data from a file using BufferedReader

 

// Java BufferedReader class is used to read the text

// from a character-based input stream.

// It can be used to read data line by line by readLine() method.

// It makes the performance fast. It inherits Reader class.

import java.io.BufferedReader;

import java.io.FileNotFoundException;

import java.io.FileReader;

import java.io.IOException;

class BufferedReaderDemo {

public static void main(String[] args)

throws FileNotFoundException, IOException {

FileReader fr = new FileReader("BufferedWriter.txt");

BufferedReader br = new BufferedReader(fr);

int data;

while ((data = br.read()) != -1) {

System.out.print((char) data);

}

System.out.println();

br.close();

}
