package org.students;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;

public class FileReadAndWrite {

   public static void main(String[] args) {
       String line=\"Hello World!\";
       try {
    //Creating FileWriter object by passing output file name as input.
    FileWriter fw=new FileWriter(\"D:\\\\hello.txt\");
    BufferedWriter bw=new BufferedWriter(fw,1024);
      
      
    //Writing the data to the txt file
bw.write(line);

//closing the buffered writer
bw.close();
//closing the file write
fw.close();

   // FileReader reads text files in the default encoding.
FileReader fileReader = new FileReader(\"D:\\\\hello.txt\");
  
//Always wrap FileReader in BufferedReader.
BufferedReader bufferedReader = new BufferedReader(fileReader);
  
//Reading the data from the file.
while((line = bufferedReader.readLine()) != null) {
  
//Displaying the data on the console
System.out.println(line);
     
}

//Closing the buffered reader
bufferedReader.close();
  
//closing the file reader
fileReader.close();
  
}
       catch(FileNotFoundException ex) {
System.out.println(\"Could\'nt able to open file \");
}
       catch(IOException ex) {
   System.out.println(\"Error reading file \");
     
   }
   }

}
