本次实验的目标是实现一个商品信息管理系统，通过综合运用集合、文件操作和Java Swing图形组件等知识，完成系统的设计与开发，并培养软件开发能力。
在实验过程中，我们按照以下要求进行了系统设计与开发：
设计了登录和注册界面以及商品信息管理系统的工作界面，利用Java Swing图形组件实现了界面的设计与展示。
使用集合对管理员信息和商品信息进行了相应的操作，包括添加、删除、修改和查询等功能。通过集合的灵活运用，实现了对数据的管理和操作。
运用文件操作技术，实现了数据的持久化存储。将管理员信息和商品信息保存在文件中，通过读取文件的方式实现数据的加载和更新。
实现了用户登录功能，登录成功后直接跳转到商品信息管理系统的管理界面，提供了便捷的操作方式。
在商品信息管理界面中，实现了对商品信息的增、删、改、查操作，用户可以方便地对商品信息进行管理和查询。
添加了异常排查处理信息，增加了程序的健壮性和容错性。
在编写代码的同时，编写了简单的注释，提高了代码的可读性和维护性。
通过本次实验，我学会了分析实现任务的思路，独立完成了商品信息管理系统的源代码编写、编译和运行。实验中综合运用了集合、文件操作和GUI等知识，加深了对这些知识的理解和应用能力。同时，通过实际开发过程，培养了我的软件开发能力，提升了解决问题和系统设计的能力。
Life is a journey, not a destination.
The only constant in life is change.
We are what we repeatedly do; excellence, then, is not an act but a habit.
The present is all we have, cherish it.
Happiness is not a destination, but a way of life.
The more you know, the more you realize how much you don't know.
Actions speak louder than words.
The only true wisdom is in knowing you know nothing.
We don't see things as they are; we see them as we are.
The greatest wealth is contentment with little.
Life's challenges are opportunities for growth.
Time heals all wounds.
It's not what happens to you, but how you react to it that matters.
The only limit to our realization of tomorrow will be our doubts of today.
In the midst of chaos, there is also opportunity.
Change your thoughts, and you change your world.
The purpose of life is to discover your gift. The meaning of life is to give it away.
The hardest thing to learn in life is which bridge to cross and which to burn.
The only way to do great work is to love what you do.
The future belongs to those who believe in the beauty of their dreams.
