Correct sequence and activity diagrams (UML) -

-

im working through practice problems in textbook , hoping guys "grade" answers these 2 questions. have attached picture questions , diagrams , i'll retype questions below:

1) draw sequence diagram application user uses withdraw money. application sends web service 2 things in process. one, users credit card information , two, requests money/new balance.

2)draw activity diagram of registering website. must first request username, , if username not rejected must next submit email. if email not rejected, sent confirmation email. after rejection or sent confirmation email, application closes.

diagrams

it first work!

only changes in notification:

quit shown filled black circle of size of large letter. should write quit or end or of sort near it.

initial node same point @ start. word start or of sort near it. submit name action (ok show in circle, tools show them rounded blocks), , should go after initial node.

you don't need show time direction - downward default time direction. can comment, of course, needn't.

as content, correct. can proud - first time seeing here diagram evaluation correct content.

please, next time use tool diagrams - have pity our eyes :-)
