IntelliJ IDEA is 20 years old, and the 2-day anniversary event is free for developers

Preface

Hello, my name is Brother A (YourBatman). Question: Brother A entered the industry in 2015 and used IntelliJ IDEA for the first time in September 2017. From the initial rejection and resistance, he can't put it down now. In a flash, IntelliJ IDEA is 20 years old. I wish it better and better. I have shared several in-depth analysis articles about IDEA in the past year, and I will share with you in advance at the beginning of the article:

• IntelliJ IDEA 2020.3 is officially released, the last version of the year is very ethical
• IntelliJ IDEA 2020.2 is officially released. There are always a few highlights that can help you improve efficiency
• IntelliJ IDEA 2020.1 is officially released, and almost everything you want is here!
• IntelliJ IDEA 2019.3 is officially released. What new features does it bring to us?
• IDEA command line shortener helps you solve this problem: Command line is too long. Shorten command line

In 2001, IntelliJ IDEA was born, making development more productive and enjoyable. In 2021, IntelliJ IDEA has been loved and used by more than 4 million developers worldwide!

IntelliJ IDEA is the most important product of JetBrains, not one of them. Looking back on its 20th anniversary, at the beginning of its establishment, JetBrains was just a small company that couldn't be more ordinary in Prague (the capital of the Czech Republic). In the beginning, there were only 3 employees, making one product to serve 800 customers. After 20 years of continuous development, the company has become a multinational company with offices in 9 countries around the world, more than 1,200 employees, 25 developer tools, and more than 8 million users.

Note: JetBrains products are aimed at developers/programmers, not ordinary C-end users, so this number is very staggering

This year (2021) is the 20th anniversary of IntelliJ IDEA. For this reason, JetBrains plans to IntelliJ IDEA Confhold a grand anniversary event, which is called it . All developers can sign up for free . The founder of the company, Maxim Shafirov, will "visit the scene." The meeting time and specific schedule will be listed later.

IntelliJ IDEA transcript

IntelliJ IDEA is global and international, and its users are located in all corners of the world. From the official statistics, you can see the branches of each state:

You can also see from the map that the number of people using IntelliJ IDEA in Asia is the most. After all, as you know China is in Asia (and India), the total number of people has always been stubbornly determined.

As of January 2021, the total population of Asia is 4.5 billion and the world is 7.7 billion, accounting for about 60%

Top 5 countries in the number of users

Is there any suspense first? Answer, no. After all, the number of people in China has not been afraid of anyone~

First place: China

Third place: India

Fourth place: Germany

Fifth place: Russia

Note: Statistics are from the whole year of 2020

Note: Statistics are from the whole year of 2020

IntelliJ platform product summary

IntelliJ is a platform, and IntelliJ IDEA is its foundation. There are also many commercial/non-commercial products, many mature IDEs and plug-ins, and put a proud product map:

Relying on IntelliJ's excellent genes and providing a powerful base, each product is excellent, and The experience can also be highly consistent.

IntelliJ IDEA market share

IntelliJ IDEA is mainly for Java developers, and the Java language IDE has three main mountains:

• Apache NetBeans
• Eclipse
• IntelliJ IDEA

The three of them have ruled the "Jiangshan" at different time stages. As a rising star, IntelliJ IDEA has become the absolute overlord at this moment (2021). The following picture is the 2020 version of the JVM Ecological Report (IDE):

In 2020, IntelliJ IDEA's market share will reach 62%, far surpassing the second-ranked Eclipse's 20%. It is worth mentioning that the well-known Eclipse has a 38% share in 2019, and it will drop to 20% in 2020, which is a huge drop. The third place NetBeans is getting weaker and weaker and it is only a matter of time before it is completely eliminated.

Note: "Variants" of Eclipse, such as Spring's STS, MyEclipse, etc., are all counted in Eclipse's share

There are two important time nodes for IntelliJ IDEA to complete the transcendence:

• 2012: The overall performance of IDEA has surpassed that of Eclipse, which provides conditions for developers to start defection
• 2016: IntelliJ IDEA's market share surpassed Eclipse for the first time, starting the road to quickly erode its remaining market share

IntelliJ IDEA vs. Eclipse

There are different opinions on whether IntelliJ IDEA or Eclipse is better. There is never an answer to this kind of question. After all, geeks still think that it is the best editor/IDE to write code in vim. This varies from person to person. I think it will be expanded. The discussion is meaningless.

However, from a big point of view, the market share data tells everything. When choosing a tool, it is always best to choose the "first place". After all, the market's choice is always wise. If you don’t define yourself as very special, it’s often safest to make this choice.

As we all know, a major feature of IntelliJ IDEA is memory consumption. Some people say that IDEA is accompanied by the rapid development of hardware performance. I personally agree with this view. It can be said that the times make heroes. Maximizing hardware performance is an important ability. With at least 8G of RAM now standard, are you still entangled with IDEA eating 1-2G of RAM? Who are you going to give IDEA if you don’t? Let it sit idle and smoke?

Brother A strictly speaking has never used Eclipse , but used STS for 2 years, and then turned to IntelliJ IDEA and never returned. If I want to recommend IDEA, use one sentence: IntelliJ IDEA really understands you and thinks what you think. It's like talking about friends, knowing what the other person means without having to say more, what a great experience.

To say that the only "disadvantage" of IntelliJ IDEA is the fee, and it is not cheap. In terms of market share , commercial charges have even done open source and free products, which are extremely rare in the industry. IntelliJ IDEA is not simple.
