Will golang replace java?

The popularity of old programming languages ​​such as Java, C, and C is gradually declining. Although it is still high, many shares have been taken away by Python, Go, etc.

Why is Java gradually being taken over by Go? First of all, Go can do everything Java can do, and even do it better. Java is now used the most for server-side development, and Go is fully capable. There are distributed, multi-threaded, microservices, RPC, etc. in Java, and it is completely true to use Go language. Our company's distributed and microservice architecture is implemented with Go, which is also very convenient and fast. The popular trends nowadays are big data, artificial intelligence, data mining, machine learning, etc. These are very troublesome to do with Java. There are corresponding programming languages ​​and frameworks, and you can naturally do it with Go. In this regard, the capabilities of Java and Go are basically equivalent.

Secondly, it is faster to develop with Go language. Programming in Java language, how do you do a simple add, delete, modify, and query business? Create an entity class JavaBean, generate a Mybatis query script, write a Service, and finally write a Controller. The entire code adds up to more than 300 lines. If written in Go language, the code level can be much simpler. Of course, the general process of developing an MVC architecture using Go is no different from that of Java.

Again, compared with the bloated and huge Java framework, Go seems very mini. Go language is an extremely simple programming language, and its framework is not as large and bloated as Java-related frameworks. Like its development efficiency, its execution efficiency is also among the best among major programming languages. It can perform countless writes in one process to ensure its efficiency. Many current microservice frameworks choose Go as the development language because it is fast and efficient.

So, is the Go language really seamless? This is not necessarily the case. There are reasons for the stable status of Java, C, and C over the years. The Java framework is stable and the technology is mature. When I want a certain technology, Java's open source framework will definitely provide a suitable technical solution, and there will never be more than one. The Go language does not have this advantage. After all, as an emerging technology, it does not have enough open source frameworks. I have used a Beego framework and it feels pretty good.

So, Go still cannot replace Java in the short term. It remains to be seen whether it will become the most popular language in the future.
