Previous reports from the Java community found that developers were still mostly using Java 8 and not adopting newer versions, but according to Snyk’s 2021 JVM Ecosystem Report, that’s starting to change. This year, 61.5% of respondents are using Java 11 somewhere in production and nearly 12% are using the latest version, which was Java 15 during the survey.
“This is huge, because it shows that developers upgrade their Java version beyond Java 8 to some extent. The mantra that most Java developers feel comfortable staying on Java 8 seems to be slowly falling apart,” Snyk said in the report.

Now does Oracle charge you for its JDK?
In 2017, developers were happily using Oracle JDK in development and production.But then Donald Smith, Senior Director of Product Management at Oracle, came out with this announcement
Oracle will continue to build and distribute Oracle JDK Oracle JDK 8 will continue to receive public updates for at least the next year, and commercial support will be available through 2025. As OpenJDK binaries become the primary channel for developers to access the latest innovation in the Java SE platform, Oracle JDK will remain as a long-term support (LTS) offering for Oracle’s commercial and support customers.
Why most companies are stuck on Java 8?
Any widely used component of an application with 500,000 lines of code that has been in development for a decade or more is extremely dangerous to update. It’s unlikely that every line of that codebase has been tested as thoroughly as it’s been used, so upgrading something as simple as the Java VM is essentially releasing something that should be treated like a brand new application, rather than an app that has been running for years, with all the stability that goes with it.
One of the major innovations of Java 8 is Java Lambda, which uses an expression to describe a single method interface. Developers can use Java Lambda expressions to write code in a functional approach. As a result, the developer saves a lot of time and effort. Java Lambda eliminates the need for developers to specify a method multiple times. “They perform in the context of their appearance”, is the most important property of Java Lambda.
New Features
First, what new features have been added in the 4 1/2 years between releases?
1. Modularity: One of the biggest changes is the modularity introduced with Java 9. Modularity allows you to split your applications into different modules, but it also changes the way java handles its API internally.
What is Java 8?
The world’s best programming platform just released Java 8, which is revolutionary. The Java programming model has been improved more significantly, and the JVM, Java language, and libraries have undergone synchronized evolution.
The forEach() method of the Iterable interface is one of the Java 8 innovations listed below:
