Java File and IO: BufferedInputStream

There are a lot of APIs regarding files and IO in Java. Some of the basics will be discussed here.

1. BufferedInputStream
2. BufferedOutputStream
3. DataInputStream
4. DataOutputStream

First let us differentiate all these.

1. BufferedInputStream :  kind of inputStream that buffers the input data in order to optimize the speed access to the data.

2. BufferedOutputStream : kind of outputStream that buffers bytes.

3. DataInputStream : is a kind of InputStream used to read data as primitive data types from an underlying input stream.

4.DataOutputStream : kinf of outputStream that allows user to write data as primitive data types.

Examples:

BufferedInputStream

import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;

public class BufferedInputStreamExample {
 public static void main(String[] args) {
           
  //Get the file to read using BufferedInputStream
        File file = new File("C://tutorialpointph//file.txt");
        BufferedInputStream bin = null;
         
        try
        {
            //obtains input bytes from the file
            FileInputStream fin = new FileInputStream(file);                  
            /*
            * creates a BufferedInputStream and saves 
            * it into the buffer array for further use
            */                  
            bin = new BufferedInputStream(fin);                                      
            //read the file 
            //available : while there are bytes to read
            while( bin.available() > 0 ){                        
             System.out.print((char)bin.read());
            }                  
         }
         catch(FileNotFoundException e){
            System.out.println("File not found on path" + e);
         }
         catch(IOException ie)
         {
            System.out.println("Exception while reading " + ie); 
           }
         finally
         {
            //close the BufferedInputStream after reading
            try{
              if(bin != null)
              bin.close();                                  
             }catch(IOException ie){
              System.out.println("Error while closing : " + ie);
             }
