variable.

if(mp.getContentType().equals(ContentType.MULTIPART_ALTERNATIVE){

for(int i=0;i<mp.getCount();i++){
BodyPart bp=mp.getBodyPart(i);

4. If a

BodyPart

object is of type

MimeBodyPart

, store the content type of the

BodyPart

object in a

String

variable.

if(bp instanceof MimeBodyPart){

for(int i=0;i<mp.getCount();i++){
BodyPart bp = mp.getBodyPart(i);
