java swing (complete a project only 3 interfaces left)

I have worked on a movie theater project I need someone to complete the rest 3 interfaces.

I want you to work on the food list, let the user to choose multiple item from the menu (the prices shown in the interfaces)

Then the user goes to the cart there will be carts id,username of the user, the price for a ticket(45 for regular,75 for VIP),the price of food items and total price ,then the user goes to bill interface showed the bill number ,date,username,ticket price,food,price,total

then go to the payment interface (which already done)

Also in the sign up interface I want you to make show message when the user enter wrong email or phone number.
