Aim:- Refine the student manager program to manipulate the student information from files by using the BufferedReader and BufferedWriter.

JAVA Code :-

import java.lang.*;

import java.io.*;

public class pra12 {

    public static void main(String[] args) throws Exception {

        BufferedReader bufRead = new BufferedReader(new FileReader("a.txt"));

        BufferedWriter bufWrite = new BufferedWriter(new FileWriter("ab.txt"));

        int i;

       

        do {

            i = bufRead.read();

            if (i != -1) {

                if (Character.isUpperCase((char) i)) {

                    bufWrite.write(Character.toLowerCase((char) i));

              }

 else {

                    bufWrite.write((char) i);

                }

            }

        } while (i != -1);

        

        bufRead.close();

        bufWrite.close();

    }

}
