Java read file by char using FileReader

public class FileReader extends InputStreamReader
Convenience class for reading character files. The constructors of this class assume that the default character encoding and the default byte-buffer size are appropriate. To specify these values yourself, construct an InputStreamReader on a FileInputStream.
FileReader is meant for reading streams of characters. For reading streams of raw bytes, consider using a FileInputStream.

package com.candidjava.file;

import java.io.File;
import java.io.FileReader;

public class FileRead {
  public static void main(String[] args) throws Exception {
    File file=new File("F:/Files/read.txt");
    FileReader fr=new FileReader(file);
      int i;
    while((i=fr.read())!=-1)
    {
      System.out.println((char)i);
    }
    fr.close();
  }
