Multithreading and high concurrency
The following are a few questions about multithreading and high concurrency in interviews with big factories. I wonder if everyone here will do it?
- Talk about the synchronized CPU primitive level implementation
- There are ten million numbers, write a program for efficient summation
- Knowing that the square root of 2 is 1.414, how to find the square root of the value without using the math library, accurate to 10 digits after the decimal point
- The coding implements two threads. Thread A continuously prints numbers from 1 to 10, and requires that thread B be notified when the fifth number is printed.
- Which 7 parameters need to be specified for a custom thread pool, why is it not recommended to use the built-in thread pool of JUC?
- How to use thread pools for businesses with high concurrency and short task execution time?
- How do businesses with low concurrency and long task execution time use thread pools?
- How to use thread pool for business with high concurrency and long business execution time?
- Design a 12306 website that can hold up to one million TPS (Taobao up to 540,000 TPS). How do you achieve it?
If you only have experience in CRUD and never understand multi-threading and high concurrency, I believe you must be at a loss.
The first document shared by the editor today is "Multithreading and High Concurrency". These two areas are now more and more asked in interviews, and they must be stepped through for a junior programmer to advance to the middle and advanced levels. A hurdle. This book will take you to systematize the knowledge of multithreading, help you understand the realization of multithreading at the CPU level, and how these realizations map layer by layer to those systems with hundreds of millions of users, tens of millions of QPS, and millions of TPS.
Sweep all the questions about multi-threading and slap all interviewers who dare to ask concurrent questions. (Don’t worry about the interviewer)
This book is a book that uses relatively colloquial text, which is easy to understand, so that readers and friends can spend less time doing the most effective learning.
Because the copy is too long, I won’t give you a detailed introduction here, and show it to you in the form of screenshots. Friends who are interested in learning high concurrency, multithreading, distributed, and microservice combat

Distributed and microservices are almost the architectural directions that today's technical personnel must understand. In theory, it does explain a lot of structure, but on the other hand, it will bring more derivative complexity and difficulties. In the face of increasingly complex systems and businesses, distributed technology has long become a must-learn technology in the Internet era. However, if we have not experienced the practice and experience of a large company background, it is difficult for us to touch the design and architecture of distributed services .
springcloud microservice
In recent years, microservice architecture has become a hot topic in the IT field. A large number of first-tier Internet companies have invested in the construction of microservice architecture due to their huge business volume and business needs. Large companies such as Alibaba, Baidu, and Meituan have already started the practice and application of microservices very early.
Starting from the popular concept of microservice architecture, this book introduces Spring Cloud's solutions and basic components for several core elements of microservice architecture in detail. For the introduction of each component, this book mainly combines examples and source code to help readers better understand the usage and operating principles of these components. At the same time, in the process of introduction, some problems and solutions encountered by the author in practice are also included, which can be used as a reference for readers in practice.
Suitable for all Java developers, especially for teams who are doing microservice architecture technology selection or are implementing microservice architecture for review and reference
