Converting Image to Byte Array and then to String

Question

Hi All...
Can anyone please help me. I have got a problem while converting a Byte array of BufferedImage to String.
This is my code, First i convert a BufferedImage to a byte array using ImageIO.wirte
public String dirName="C:\\image";
ByteArrayOutputStream baos=new ByteArrayOutputStream(1000);
BufferedImage img=ImageIO.read(new File(dirName,"red.jpg"));
ImageIO.write(img, "jpg", baos);
baos.flush();
byte[] resultimage=baos.toByteArray();
baos.close();
Then i tried to convert this byte array to a string
String str=new String(resultimage);
byte[] b=str.getBytes();
This much worked fine. But when i reversed this process to re-create the image from that string. i found the image distroted.
BufferedImage imag=ImageIO.read(new ByteArrayInputStream(b));
ImageIO.write(imag, "jpg", new File(dirName,"snap.jpg"));
I got this snap.jpg as distroted.
Please help me i have to convert the image to a string and again i have to re-create the image from that string.

To conver the bytearray to string use base64.encoding
String base64String= Base64.encode(baos.toByteArray());
To convert back use Base64.decode;
byte[] bytearray = Base64.decode(base64String);
BufferedImage imag=ImageIO.read(bytearray);
