1. Specifically InputReader can covert bytes in different encodings to characters.
--
2. BufferedReader has a back-end reader which speeds up reading if you are only retrieving small parts at a time.
3. BufferedReader can mark a given position, and after already reading the bytes, reset back to the previous position.


Try googling "Java bufferedReader class" and "Java InputStreamReader class"

To read keys from the keyboard, you usually construct an InputStreamReader stream from System.in and then use the InputStreamReader class’s read method to read what the user has typed.
For Example--

import java.io.*;
public class inputstreamreader
{
    public static void main(String args[]) throws IOException 
    {    
        char[] c=new char[10];        
        InputStreamReader isr=new InputStreamReader(System.in);
        isr.read(c,0,9); 
        for(int i=0;i<c.length;i++)
            System.out.print((char)c[i]);
        isr.close();
    }
}

The BufferedReader class provides a buffered character reader class. One of its advantages is that BufferedReader provides the readLine method. This method reads the file line by line instead of character by character.

for example--

import java.io.*;
public class bufferedreader
{
    public static void main(String args[]) throws IOException 
    {
        FileReader fr=new FileReader("bufferedreader.java");
        BufferedReader br=new BufferedReader(fr);
        String str;
        while((str=br.readLine())!=null)
            System.out.println(str);
        fr.close();
    }
}
