“To celebrate Java’s 25th anniversary this year and the latest release of Java 15, JetBrains has compiled data from multiple sources to look at what the current state of the language,” reports
The largest concentration of Java developers is in Asia, where 2.5 million developers use it as their primary language. JetBrains believes this may be due to the fact that it is common to hire offshore developers in countries like China and India to build Android apps. “We might have expected the USA to have a high percentage of Java users, but it also makes a lot of sense that they don’t. There is a big technology stack to choose from and often a lot of the tech companies are at the forefront of that stack, so it could be that developers there don’t need the power or stability of Java and are using languages that allow them to build and test quickly,” JetBrains wrote in a post.
The post on JetBrains notes that the six countries with the highest percentage of developers using Java as their primary language are: China, South Korea, India, Germany, Spain, and Brazil:
The reasons Java is most likely so popular in the first 6 countries include the free use of Java, governmental support, and open-source… Germany is also very high which could be attributed to Java being the most popular language in Germany for software engineers as it is used to build highly scalable applications for a multitude of industries. Most enterprise services rely on Java to power the applications that enable the day-to-day running of businesses, such as payroll, inventory management, reporting, and so on. Germany also has a big financial sector that uses Java heavily for their homegrown tech, such as trading bots, retail banking systems, and other applications that the finance industry requires in order to remain competitive…
As to why I think Java is so high in the sphere of professional development — it’s similar to what was mentioned about Germany. Most enterprise business services rely on Java to make them tick along. It’s not just the IT sector either — almost every company, be it in distribution, manufacturing, or banking, has IT services as part of their infrastructure, and these services, such as payroll or inventory management, are generally built with Java in the backend. So Java is used a lot by professional developers who work for these companies.
