根据自己所学科技英文相关知识和结合自己经历，用英语写一篇修完“面向对象程序设计 Java 课程”所学到知识内容、掌握什么技能、自己通过 Java 语言开发了什么程序或项目，以及对Java未来发展展望等等介绍的短文。（字数不少于200个单词，非软工专业，以C语言为题）

I recently completed a course on "Object-Oriented Programming in Java". Through this course, I learned about the fundamental concepts of object-oriented programming and how to apply them using the Java programming language.

One of the key skills I acquired is the ability to design and implement classes and objects in Java. I learned how to define class properties and methods, as well as how to use inheritance and polymorphism to create more complex and flexible object models. I also learned about exception handling and how to handle errors in a Java program.

In addition to the theoretical concepts, I also had the opportunity to apply my newfound knowledge by developing several small Java programs and projects. For example, I built a simple text-based adventure game and a student management system. These projects allowed me to put into practice the concepts I learned and helped me better understand how to apply them in real-world scenarios.

As for the future of Java, I believe it will continue to be a widely-used programming language, especially in the development of enterprise-level applications and mobile applications. With its strong performance, ease of use, and compatibility with a wide range of platforms, Java has proven to be a highly effective and versatile programming language.

In conclusion, the course on "Object-Oriented Programming in Java" was a valuable learning experience for me. Through this course, I was able to deepen my understanding of object-oriented programming concepts and gain hands-on experience in Java programming. I am confident that the skills and knowledge I acquired will be useful in my future software development endeavors.
