I need help with adding these to my existing code in java fx$.$ no swing or awt please. I provided my existing code and a picture of the expected outcome.

Ex$01$: Enhance your $$Dorm$,$ Meal, Others Calculator$$ app by providing a send an $$order confirmation

email$$ function through Gmail if a customer chosen to do so$.$ If necessary, refer to reference$-1.$a for

how$-$to use Java code to send an email through a Gmail account.

$$ What do you need to do:

a$.$ Enhance your app so it will send an order confirmation email through your free Gmail

account if a customer puts a $$Check mark$$ checkbox and an Email on the textfield control

and then click the $$Place Order$$ button.

Refer to the screenshot below.

$1.$ To keep things simple, we just assume that when the $$Place Order$$ button is clicked, a

user has some item$($s$),$ a payment type, email checkbox checked, and email filled already.

b$.$ Add a prompt text $$Your Email address here$($note: don$$t use the setText$()$ method to do

this$)$ to the email textfield and an addition message $$Email sent!$$ to your Total Cost output

control to let the user know that the email has been sent

c$.$ Enhance the $$Clear All$$ function to also remove the email checkbox and email address, if any.

d$.$ Make sure the order confirmation email includes the following messages $($refer to the

screenshot below$)$:

$1.$In the subject: Your order placed at $[$the ordered date and time$]$

$2.$In the body:

$1.$ Dorm and price $($if any$),$ Meal Plan and price $($if any$),$ Options and prices $($if

any$),$ Total amount, Payment Type, Thank you for your business.

f$.$ Make sure that the appearance of your app resembles to the ones on the screenshots or in the

demonstration video.

g$.$ Verify the correctness of your app to produce the expected results.
