Convert InputStream to File

Here we are showing how to convert an InputStream to File.

To do so first read the file as InputStream using FileInputStream. Create FileOutputStream class object to retrieve the file from system for modification then convert the InputSteam into byte array before writing into file then pass this array to the input stream and finally the byte array into file. Now all the data from InputStream is written into the desired file.

The code of the program is given below:


import java.io.*;

public class InputStreamToFile

  {

  public static void main(String args[])

  {

  try

  {

  File f=new File("outFile.java");

  InputStream inputStream= new FileInputStream

("InputStreamToFile.java");

  OutputStream out=new FileOutputStream(f);

  byte buf[]=new byte[1024];

  int len;

  while((len=inputStream.read(buf))>0)

  out.write(buf,0,len);

  out.close();

  inputStream.close();

  System.out.println("\nFile is created........

...........................");

  }

  catch (IOException e){}

  }

  }

The output of the program is given below:

C:\rajesh\io>javac InputStreamToFile.java

C:\rajesh\io>java InputStreamToFile

File is created.......................
