Looking at this year's technical recruitment market, Java is still the undisputed overlord ! Even if it is constantly impacted by emerging languages such as Go, it still remains unchanged. The reason:
- Java has an extremely mature ecosystem, and I don’t need to say more about this;
- Java has excellent performance in operation and maintenance, observability, and monitorability;
- Java is also actively responding to major trends such as containerization and cloud native. For example, Spring Boot has fully embraced cloud native.
Enterprises have the largest demand for Java , and the group of Java programmers is also the largest, with as many as 12 million , and each has more choices.
In other words, it is also the most Shura field!
Therefore, if we want to get the offer we want , we must be well prepared and thoroughly understand all the required test points and routines!
I brought together a few big guys to summarize the situation of the first-tier manufacturers and compiled a set of super comprehensive interview materials for you: 1658 pages of Java interview surprise core lectures . It also contains a relatively wide range of knowledge points: Java basics, JVM, Multi-threading, MySQL, spring, springboot, springcloud, dubbo, mybatis, redis, network IO, Linux, MQ, zookeeper, netty, big data, algorithms, projects, design patterns, etc.; after finishing this set of high-quality questions , This gold, nine, silver and ten is perfect~
