Question
I'm making a Java program that allows a user the ability to choose one product inside a vending machine then allows the user the ability
I'm making a Java program that allows a user the ability to choose one product inside a vending machine then allows the user the ability to print the whole day transaction or receipt of the vending machine. I want to print out the receipt that will include the name and the cost of each of the products ordered. I found that using an array is the only way I can get the items ordered in a list format. Help and suggestions would really be appreciated. Keep in mind that I cant do advanced stuff. I posted my program below.
