Create a UML for the IcecreamStore class before coding $($use a pencil, pen, or ruler$)$

Develop a class called IcecreamStore that will use array fields to store the username and password, names of the items, and their unit costs. It will also contain a field for tax with a rate of $8\%.$ You should create three arrays namely a $2-$dimensional array for the username and password with entries username, password, and $$Baskin$$ and $100$ Chambers$$ respectively. A regular array for the items$$ names $($you create any $4$ types$)$ and another array for the items$$ prices $($You create any $4$ prices$).$ In addition, the class will contain $7$ methods: one to return the username, another to return the password, another to return a price given an item name, another to return the names of the items, another to calculate the cost, another to calculate the taxes, and another to calculate the total cost. $($Note: you will need to determine the parameters and return types of your methods$)$

Develop a JavaFX application that uses the IcecreamStore class. The program will do the following: $($Note: you will have to use the methods in the IcecreamStore class in the demo$)$

Ask a user to enter her username and password. If it is correct it will proceed to b$,$ otherwise, it will prompt the user until the entries are correct. You should use any controls to do this.

displays a menu of the list of items and their costs, sold by the pizza store. You can use a gridpane.

Accept an item and quantity to buy from the user. You can use textfields.

After the user clicks a button, it will display the pre$-$cost of the items, the taxes on the item, and the total cost

Include user validation for all your user data entries
