Move single email message from inbox to another folder

Hi everyone,

I would like some code to move a SINGLE email message from the inbox
to another one.

I have code to move a group of them:

folder.copyMessage(messages, SomeOtherFolder);

but what I would like to do is:

folder.copyMessage(messages[i], SomeOtherFolder);

the idea being that as I iterate through each message, I can file them
away in the appropriate folder.

code snippet:

//logon to pop3 server
//connect to store
//open inbox folder

Message messages[] = inboxFolder.getMessages();
for (int i=0, n=messages.length; i<n; i++)
{
//do some code to process subject line, body, sender etc
//save message body and any attachments to database
//then move it to the correct folder

if (SaveFlag)
//move this message to the SaveSuccessful folder
else
//move it to SaveFailed folder

}

//close everything and clean up

Any and all help appreciated.

copyMessage implies that the function copies *a* message, not *many*
messages.

One message can be trivially converted into an array:
Message uniMessage[] = new Messages[] {messages[i]};

A better tactic would be to keep two lists:
LinkedList<Message> successful = new LinkedList<Message>();
LinkedList<Message> failed = new LinkedList<Message>();
for (Message m : messages) {
if (saveFlag)
successful.add(m);
else
failed.add(m);
}
folder.copyMessages(successful.toArray(new Message[0]));
folder.copyMessages(failed.toArray(new Message[0]));
