Reading data from console and writing data on console using FileInputStream and FileOutputStream

 

/*If you have to write primitive values into a file,

use FileOutputStream class. You can write byte-oriented as well as character-oriented

data through FileOutputStream class. But, for character-oriented data,

it is preferred to use FileWriter than FileOutputStream.*/

import java.io.FileInputStream;

import java.io.FileNotFoundException;

import java.io.FileOutputStream;

import java.io.IOException;

class FileCopy1 {

public static void main(String[] args)

throws FileNotFoundException, IOException {

FileOutputStream fos = new FileOutputStream(args[1]);

while ((data = fis.read()) != -1) {

fos.write(data);

}

System.out.println("File Copied");
