Pizza添加Toppings部分填充数组java

Question

我不知道在我的阵列中添加一个新的顶级名称，最后我必须添加元素但是我不知道在哪里使用循环到目前为止我在我的代码中有这个。谢谢 - 这个项目背后的想法是你将使用一个部分填充的数组来维护一系列的披萨配料。将有一个固定的可用配料列表供用户选择。用户将能够添加/删除浇头列表中的浇头，这是输出：

Currently no toppings selected
Enter Option: (A-Add Topping; R-Remove Topping; X-Exit): a
Possible toppings are:
0 Sausage
1 Pepper
2 Pepperoni
3 Brocolli  didn’t realize I misspelled it until pasting into Word…sigh
4 Tomatoes
5 Eggplant
6 Meatballs
7 Ham
8 Pineapple
9 Bacon
Enter # of topping to add: 6
Toppings Selected:
0 Meatballs
Enter Option: (A-Add Topping; R-Remove Topping; X-Exit): a
Possible toppings are:
0 Sausage
1 Pepper
2 Pepperoni
3 Brocolli
4 Tomatoes
5 Eggplant
6 Meatballs
7 Ham
8 Pineapple
9 Bacon
Enter # of topping to add: 0
Toppings Selected:
0 Meatballs
1 Sausage
Enter Option: (A-Add Topping; R-Remove Topping; X-Exit): a
Possible toppings are:
0 Sausage
