Ali's achievements today depend largely on the talent accumulation and outstanding creativity of Ali's technology department. You must know that a new programmer will grow very fast after entering Ali, because many technical experts in Ali content will produce some training materials based on their years of development experience.
There are very few Ali internal training materials on the market, and they are all scattered. In the front-end time, a P7 employee in Ali integrated the training materials of Ali in the second half of 2021, and summarized this set of "Java Evil Sword Manual"
The entire manual is divided into seven chapters, namely: High Concurrency, Distributed, Middleware, Database, Design Patterns, Data Structure and Algorithms, and Summary of Alibaba's Annual Interview Questions!
