Example

The following example shows the usage of java.io.BufferedInputStream.read() method.

package com.tutorialspoint;

import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.InputStream;

public class BufferedInputStreamDemo {
   public static void main(String[] args) throws Exception {
      
      InputStream inStream = null;
      BufferedInputStream bis = null;
      
      try{
         // open input stream test.txt for reading purpose.
         inStream = new FileInputStream("c:/test.txt");

         // input stream is converted to buffered input stream
         bis = new BufferedInputStream(inStream);			

         // read until a single byte is available
         while(bis.available()>0)
         {
            // read the byte and convert the integer to character
            char c = (char)bis.read();

            // print the characters
            System.out.println("Char: "+c);;
         }
      }catch(Exception e){
         // if any I/O error occurs
         e.printStackTrace();
      }finally{		
         // releases any system resources associated with the stream
         if(inStream!=null)
            inStream.close();
         if(bis!=null)
            bis.close();
      }
   }
}

Assuming we have a text file c:/test.txt, which has the following content. This file will be used as an input for our example program:

ABCDE  

Let us compile and run the above program, this will produce the following result:

Char: A
Char: B
Char: C
Char: D
Char: E
