Working with FileReader

 FileReaderclass creates a Reader that can be used to read the contents of a file.

 Its two most commonly used constructors are:

FileReader(String filePath)

FileReader(File fileObj)

It can throw a FileNotFoundException.

Here, filePath is the full path name of the file, and fileObj is a File object that describes the file.

 Example:

import java.io.*;

classFilereader

{

public static void main(String args[]) throws IOException

 {

FileReader f=new FileReader("File1.txt");

BufferedReader b=new BufferedReader(f);

  String s;

while((s=b.readLine())!=null)

System.out.println(s);

 }

}

Output:

Hello this is written to the file using print stream

Again the next line is also written to the file
