java - Convert file to byte array and vice versa

Question

I've found many ways of converting a file to a byte array and writing byte array to a file on storage.

What I want is to convert java.io.File to a byte array and then convert a byte array back to a java.io.File.

I don't want to write it out to storage like the following:

//convert array of bytes into file
FileOutputStream fileOuputStream = new FileOutputStream("C:\testing2.txt"); 
fileOuputStream.write(bFile);
fileOuputStream.close();

I want to somehow do the following:

File myFile = ConvertfromByteArray(bytes);

Otherwise Try this :

Converting File To Bytes

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


   public class Temp {

        public static void main(String[] args) {

         File file = new File("c:/EventItemBroker.java");

         byte[] b = new byte[(int) file.length()];
         try {
               FileInputStream fileInputStream = new FileInputStream(file);
               fileInputStream.read(b);
               for (int i = 0; i < b.length; i++) {
                           System.out.print((char)b[i]);
                }
          } catch (FileNotFoundException e) {
                      System.out.println("File Not Found.");
                      e.printStackTrace();
          }
          catch (IOException e1) {
                   System.out.println("Error Reading The File.");
                    e1.printStackTrace();
          }

       }
    }

Converting Bytes to File

      public class WriteByteArrayToFile {

         public static void main(String[] args) {

            String strFilePath = "Your path";
            try {
                 FileOutputStream fos = new FileOutputStream(strFilePath);
                 String strContent = "Write File using Java ";

                 fos.write(strContent.getBytes());
                 fos.close();
           }
          catch(FileNotFoundException ex)   {
                 System.out.println("FileNotFoundException : " + ex);
          }
         catch(IOException ioe)  {
                 System.out.println("IOException : " + ioe);
          }

       }
     }
