store and retrieve image data to any database in java

We will insert image data into database in byte[] format

Here is a piece of code to convert image data into byte[]:

 // image file

File file = new File("images/extjsfirstlook.jpg");  

// create byte with specified size 

byte[] bFile = new byte[(int) file.length()]; 

try {  

  FileInputStream fileInputStream = new FileInputStream(file); 

  // bFile is initialized

  fileInputStream.read(bFile);

  fileInputStream.close();

   } catch (Exception e) {

 e.printStackTrace(); 

 }

//now you can store bFile in database

Here is a piece of code to convert byte[] data into image:

try {  

    // create output stream with a file path where you want to store 

    // your image on your drive

    FileOutputStream fos = FileOutputStream("images/output.jpg");

    // it will write data byte data into the file specified 

    fos.write(book.getImage());

    fos.close()
   } catch (Exception e) {


  e.printStackTrace(); 

}

// now you can use your image
