The Java core study notes compiled by Ali P8 Daniel. After 2 months of eating thoroughly, I was fortunate to receive 7 offers in a row

Preface

Some people may lament that some people have better luck, but they never know how much the other person has suffered or suffered. Sometimes it is necessary for us to deliberately discover the breakthrough point, and then follow the trend to seize the opportunity, then you will take another road and achieve another brand new self.

Judging from the current environment, the difficulty of interviews is much higher than in previous years. An obvious feeling: This year's autumn move, both on one side and on the other, will test the technical skills of Java programmers. And I was fortunate enough to get the Java core study notes shared by the Alibaba P8 architects. It took me a month and a half to study. After the interview, I was full of confidence. I successively got seven offers from major manufacturers such as JD.com, Meituan and Ali. . Share the notes here, hoping to help more people who love to learn, and also help more people to get an offer during the interview smoothly, enter their favorite big factory, and be a better self.

The notes are from Ali P8-level architects, and the general content includes Java collections, JVM, multithreading, concurrent programming, design patterns, Spring family buckets, Java, MyBatis, ZooKeeper, Dubbo, Elasticsearch, Memcached, MongoDB, Redis, MySQL, RabbitMQ, Kafka, Linux, Netty, Tomcat and other big companies interview questions and technology stack! Clearly organized and easy to understand including graphical representation
