Copying a file with java using Input/Output Stream

Description:

The piece of code below shows you how to copy two files using Java. We're going to use basic java classes, mainly they are: FileInputStream and FileOutputStream.

Solution:

package com.javaproblems.binaryfiles;

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

public class BinaryFileCopy {

 
 public static void main(String[] args) {
  try {
   File f1 = new File("MyPhoto.jpg");
   File f2 = new File("TrgtMyPhoto.jpg");
   
   FileInputStream in = new FileInputStream(f1);
   FileOutputStream out = new FileOutputStream(f2);
   
   byte[] buf = new byte[1024];
   int len;
   
   while ((len=in.read(buf)) > 0) {
    out.write(buf, 0, len);
   }
   
   in.close();
   out.close();
  } catch (FileNotFoundException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  
  

 }

}
