Buffered Input Stream

This class is used to read information from stream. To make the performance fast, it internally uses buffer mechanism. Internal buffer array gets created when a BufferedInputStream is created.

Syntax for declaring java.io.BufferedInputStream class:

public class BufferedInputStream extends FilterInputStream

Example:

Create a text file named text1 in D drive with following data(Any data can be written):
I love Coding!!
Save and test the program for the execution.

Points to be noted in Buffered Input Stream

An array is internally created during the creation of BufferedInputStream

While reading the bytes, array internally is filled automatically if the bytes are skipped

Class declaration:

Following is the syntax for java.io.BufferedInputStream class is

public class BufferedInputStream extends FilterInputStream

Constructors in Java BufferedInputStream

Constructor	Short Description of the constructor
BufferedInputStream(InputStream IS)	Creation of BufferedInputStream
BufferedInputStream(InputStream IS, int size)	Creation of BufferedInputStream with definite size

Methods in BufferedInputStream

Name of Method	Short Description of the method
int read( )	To read the data from the input stream
int available()	Returns the estimation of available bytes
int read(byte[] b, int off, int In)	Read the specified byte type into a specified byte array
void close()	Performs close and release the resource utilized by it
void reset()	It place back the stream in the previously called position

Example :

       
import java.io.*;  
public class BufferedInputStreamExample{    
 public static void main(String args[]){    
  try{    
    FileInputStream fin=new FileInputStream("knowledge2life.txt");    
    BufferedInputStream bin=new BufferedInputStream(fin);    
    int i;    
    while((i=bin.read())!=-1){    
     System.out.print((char)i);    
    }    
    bin.close();    
    fin.close();    
  }catch(Exception e){System.out.println(e);}    
 }    
}
