我希望我的 jRadioButtons 有一个 JOptionPane 数量

Question

我有一个程序包含 15 个 jRadioButton，它们是 phone 个产品，jButton 用于计算总金额，以及一个购买按钮。该程序运行平稳，并实际计算所选单选按钮的总和。唯一欠缺的就是数量。我希望程序能够选择所选产品的数量（例如 "Iphone 6" "How many do you wish to buy?"）。然后，点击"Total amount"后，它会计算，包括数量（ex. "Iphone6" "How many: 6" "Samsung S5" "How many:4" "total Amount" "The sum of the products").
