Now the value of mid-February, but most companies still have not started due to the epidemic, many people are still at home with home or remote office, in fact, for those people who intend to quit, now is the "closed-door practice." a good time, but many people do not know where to start learning, but also positive for the upcoming gold and three silver four to worry about! Today, Xiao Bian will share this year's Raiders pass through the interview, read the Java technology stack, so you gold and three silver four over five slay six.

The Java technology stack into a book (including: VM, JAVA collection, JAVA multi-threaded, JAVA foundation, Spring principle, micro-services, Netty and RPC, network, logs, Zookeeper, Kafka, RabbitMQ, Hbase, MongoDB, Cassandra, design mode, load balancing, database, consistent hashing, JAVA algorithms, data structures, encryption algorithms, distributed caching, Hadoop, Spark, Storm, YARN, machine learning, cloud computing), for your interview go a long way, so you offer hand, there are well-paid!
