我如何才能使此文本字段和下拉菜单正常工作以完成我想要的工作？

Question

我不希望有人为我做这项工作，但是我很难自行寻找问题的确切答案。我正在尝试创建一个文本字段，用户必须在其中输入1到3之间的一个整数，然后输入一个下拉菜单来选择口味（想使用下拉菜单作为提交方式或获取菜单的方式）本身保持选中状态）。提交后，我希望弹出一个带有彩绘冰淇淋圆锥形的窗口，该圆锥形会根据口味和勺子的数量来改变颜色，从而也能准确地适应用户的输入。

我一直在尝试与JOptionPanel一起工作，因为我认为也许与某种ActionListener设置相结合可以为我解决问题，但是我似乎找不到所需的方法或建议。工作就是这样完成的。
