The day before yesterday, I wanted to go to github to exchange technical issues, and by the way, I would like to play with the source code. As a result, I accidentally opened the blog of a friend of Ali. There are a lot of weird comments under his document:
What PHP is the best language in the world~
Python is a language that can go to heaven~
Java is the most invincible~
C++ despises all Gonang cowhide~
This view can still be seen everywhere on the Internet!
However, when we are talking about good and bad programming languages. have you ever thought about
Language itself is a tool for the utilization of computer resources
resource
It refers to [cpu, memory, disk, network] referred to as computer resources, storage resources and network resources
Think about it, are all your projects like this: network requests, processing data, saving data, and responding to results. So, put aside the essence of things, talk about the pros and cons of programming languages ----- just play hooligans
Therefore, rather than saying that programming languages are good or bad, it is better to say that some people do not distinguish the usage scenarios of the language, and they are making a fuss there~
Learning a language and using it well is crucial!
The editor also said before that if a programming language is a tool, then java is the best interpretation
Because java is really easy to use. Java is a sufficiently "general" language. It may not work in some specific fields, but it is sufficient for most fields. Not all scenarios have super high performance, real-time, Small size requirements, just enough.
I am an old programmer who has been engaged in development for 6 years, and java is also a language I have been working on
On the TIOBE rankings, java is often in the first position.
Here I have also compiled a set of very clear learning routes for you.
Java learning route summary
The technical points in all directions of java are sorted out to form a summary of knowledge points in various fields. Its usefulness lies in that you can find corresponding learning resources according to the above knowledge points to ensure that you can learn more comprehensively.
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!

High Concurrency
The core idea of seckill: filter layer by layer
Try to intercept requests upstream to reduce downstream pressure
Make full use of the cache and message queue to improve the request processing speed and the role of peak-shaving and valley-filling
Difficulties and solutions for large-scale Internet applications (big data, high concurrency, and diverse data types)
Distributed articles
Middleware
Sort the results according to the relevance of the obtained documents and the query statement
Database
Design Patterns
factory pattern
simple factory
Data Structure and Algorithm
Analyze the put method of HashMap
Summary of Alibaba's 2021 annual interview questions

Summarize
Opportunities are reserved for those who are prepared, so it is never too early to prepare in advance. What you learn now will eventually be useful someday in the future. So ape friends, let's learn, success will definitely belong to you!
