Short Bio 简介

My passion for multithreading and concurrency started in college, where I worked on a highly scalable, distributed B+ Tree research project sponsored by IBM.
我对多线程和并发的热情始于大学，在那里我参与了一个由 IBM 赞助的高度可扩展的分布式 B+ 树研究项目。

Later I worked as a Computer Architecture Engineer at Intel Corporation and as a Software Engineer in other companies, where I developed many applications and features involving efficient and optimized multithreaded code to deliver real-time video, audio, and data – in education, healthcare, augmented reality, and Ad Tech.
后来，我在英特尔公司担任计算机架构工程师，并在其他公司担任软件工程师，在那里我开发了许多应用程序和功能，涉及高效和优化的多线程代码，以提供实时视频、音频和数据 – 在教育、医疗保健、增强现实和广告技术领域。

Today I am a Principal Software Engineer and Software Architect. Training and mentoring engineers on all levels are both my job and my passion.
今天，我是一名首席软件工程师和软件架构师。培训和指导各级工程师既是我的工作，也是我的热情所在。

FAQs 常见问题

– “Will the course help me with interview questions?”
– “这门课程能帮助我解决面试问题吗？”

Yes! The course is focused on helping you become proficient in multithreading and concurrency in general and also master multithreading in Java in particular. You will learn all you need about threads in Java as well as common topics in interview questions involving locking, synchronization in Java, heap and stack memory organization, and so on. Although the course is not focused on interview questions specifically, and there’s no way to predict what you will be asked during an interview question, the knowledge you will get will definitely set you apart from other candidates.
是的！该课程的重点是帮助您精通多线程和并发，特别是掌握 Java 中的多线程。您将学习有关 Java 中线程的所有信息，以及涉及锁定、Java 同步、堆和堆栈内存组织等面试问题的常见主题。虽然该课程并不专门针对面试问题，也无法预测您在面试问题中会被问到什么，但您将获得的知识肯定会让您与其他候选人区分开来。

– “Does the course cover all threading classes and APIs in Java?”
– “这门课程是否涵盖了 Java 中的所有线程类和 API？”

“No. There are many books and expensive academic courses which cover EVERY single class and API which would take months to finish. In addition, Oracle provides excellent Java Docs that cover and explain every single Java multithreading API and class.
“不。有许多书籍和昂贵的学术课程涵盖了需要几个月才能完成的每门课程和 API。此外，Oracle 还提供了出色的 Java 文档，涵盖并解释了每个 Java 多线程 API 和类。

– “What if I don’t understand something during the course and I have a question, what do I do?”
– “如果我在课程中不明白什么，我有问题，我该怎么办？”

Not a problem! I am here to help you succeed! Multithreading is not an easy topic; no one is expected to get it all right away. Each lecture has a Q&A section where students can ask questions about the lecture or any follow-up questions about the topic in general. I will answer all the questions promptly and ensure you have all the tools for success.
没问题！我是来帮你成功的！多线程并不是一个容易的话题;预计没有人会立即得到这一切。每节课都有一个问答部分，学生可以在其中提出有关讲座的问题或有关该主题的任何后续问题。我将及时回答所有问题，并确保您拥有成功的所有工具。

– “Does the course cover interprocess communication and distributed Systems?”
– “该课程是否涵盖进程间通信和分布式系统？”

No. Although those are really interesting and important topics that involve concurrency. They are not directly related to Java multithreading, which is the main topic of the course. We do mention those topics during the course, but they are out of scope and deserve their own course. The concepts, use cases, and challenges are very different than the ones we encounter while optimizing the performance of a single multithreaded Java application, algorithm, or library, so we will not cover them here.
不。尽管这些都是涉及并发的非常有趣和重要的主题。它们与 Java 多线程没有直接关系，而 Java 多线程是本课程的主题。我们确实在课程中提到了这些主题，但它们超出了范围，值得单独学习。这些概念、用例和挑战与我们在优化单个多线程 Java 应用程序、算法或库的性能时遇到的概念、用例和挑战大不相同，因此我们在这里不介绍它们。

– “Why do I need a separate course for concurrent programming?”
– “为什么我需要一门单独的并发编程课程？”

Concurrent programming is fundamentally different than transitional sequential programming. As in every engineering decision, there’s always a tradeoff. Parallel and Concurrent programming can have a tremendous positive impact on the application’s performance and responsiveness but it is a lot harder to get it right. In this course, we will learn all the caveats, techniques, and best practices to get the most out of multithreaded applications in Java.
并发编程与过渡顺序编程有根本的不同。与每个工程决策一样，总需要权衡取舍。并行和并发编程可以对应用程序的性能和响应能力产生巨大的积极影响，但要做到这一点要困难得多。在本课程中，我们将学习所有注意事项、技术和最佳实践，以充分利用 Java 中的多线程应用程序。
