It covers a wide range of contents , Contains 14 A technology stack : Including the latest interview questions of major factories and face-to-face experience , And it's about JVM,Mysql, Concurrent ,Spring,Mybatis,Redis,MQ,Zookeeper,Netty,Dubbo,Spring Boot,Spring Cloud, Data structure and algorithm , Design patterns , Interview questions and detailed explanations of large factories in related technical fields such as network and operating system , There are also relevant interview assault series videos and learning routes .
One 、java The knowledge part
Now the interview pays special attention to many basic principles , However, many people do not understand some core principles thoroughly , Especially for Java Some core basic knowledge points of are not mastered enough , for example JVM、 Common algorithms and data structures . It's the so-called "ten thousand Zhang tall buildings rise from the ground" , Only grasp the foundation firmly , To go further , In the face of constantly updated technology, we can quickly master , At the same time in the interview 、 You can also stand out in your work ! Here's what you have to master Java The knowledge part , It's a lot of content , Are some key knowledge !!!
1.Java Basics :
2.Java aggregate :
3. Multithreaded concurrency :
4.java virtual machine (JVM):
JVM It's junior Java The only way for programmers to grow , Study JVM Before , Just know that the code is compiled into Class, Virtual machine loading Class Run it , Study JVM after , You can deeply understand the process of code from compilation to loading 、 Object creation and garbage collection in memory 、 In daily development, it can quickly locate performance problems, etc , Of course, it's also an indispensable bonus for an interview .
5、 Data structure and algorithm
Which data structures ( Line , chain , Pile up , Stack , queue ) And in Java Where is it useful .8 Big algorithm ( Time complexity , Spatial complexity , Memory ,CPU Influence ) And its application .KMP Search algorithm , Two points search , A recursive algorithm ( How to write it , Memory impact ). Count 、 Figure and its application .hash surface , And its application in practical work .
Two 、 Database part
Recommended reading :《 High performance MySQL》 《MySQL Technology insider :InnoDB Storage engine ( The first 2 edition )》
3、 ... and 、 Open source framework part
Spring As a lightweight Java Development framework , The idea of interface oriented programming runs through the whole Java System application , So in Java You are often mentioned in an interview .
Four 、 Distributed high concurrency architecture
This part is about distributed architecture knowledge , Include Redis,Zookeeper, Database performance optimization , Load balancing, etc. !
5、 ... and 、 Micro service knowledge
There are many small partners interviewed recently , I hope it can help more people successfully pass the interview of large factories , If you need to click the business card below to scan the code, you can get it for free !!!
