遍历并存储在数组列表或列表中

Question

我在项目逻辑上遇到麻烦。我需要将文本框中的用户输入（地址）保存到Arraylist或List中。然后，当用户单击“后退”按钮时，访问阵列列表或列表并显示存储的值。我在逻辑上遇到麻烦，创建了arraylist，并且当用户单击添加按钮时，值将添加到arraylist。问题是我不明白如何将存储的值一起发布，即城市，州，邮政编码，ID全部存储在数组中，后退按钮如何分配所有正确的值？我希望它位于应用程序右侧的ComboBox允许用户选择状态的位置。选择状态后，将在列表框中显示发往该状态的所有程序包的程序包ID号。我正在寻找有关如何使这项工作的建议或技巧。感谢您的任何帮助。
