The latest version of Java is Java 22 or JDK 22 released on March, 19th 2024 (follow this article to check Java version on your computer).For this reason, the Long-Term Support (LTS) versions were created, offering users extended support. So, such versions naturally become more stable and secure due to bug fixes, performance improvements and security patches.
What is the LTS version of Java : A Java LTS version, or long term support version, is a Java version that will remain the industry standard for several years. Oracle has released new Java LTS versions include Java 11, Java 17—and as of September 2023, Java 21.
Is Java 21 good
I'm excited to see that adoption of Java 17 is moving relatively quickly, but you really should be using Java 21. Java 21 is infinitely better than Java 8. It's technically superior on all fronts. It's faster, more secure, more operations-friendly, more performant and more memory efficient.
Will Java 21 be LTS : For product releases after Java SE 8, Oracle will designate only certain releases as Long-Term-Support (LTS) releases. Java SE 8, 11, 17 and 21 are LTS releases. Oracle intends to make future LTS releases every two years meaning the next planned LTS release is Java 25 in September 2025.
Java 21 is infinitely better than Java 8. It's technically superior on all fronts. It's faster, more secure, more operations-friendly, more performant and more memory efficient.
Java 17 includes some performance improvements over Java 11. These enhancements stem from a better garbage collector, enhancements to the JIT compiler, and improved class data sharing, leading to faster startup times and better overall performance.
Is Java 21 Long Term Support
Oracle will offer long term support for Java 21 for at least eight years. This extended support period gives organizations flexibility to keep applications in production longer with minimal maintenance, and to eventually migrate on their own terms.Java 17 (Temurin) was in most tests relative the same, but in 3 benchmarks faster, while in 3 other tests slower than Java 21. Java 22 was in most benchmarks the slowest, but as this was only an early access version, it doesn't mean that much (especially as this was running on a laptop).Java 21 is no long-term support version because it's not something that can get long-term support. JDK 21 could but only OpenJDK can make decisions about JDK and id doesn't offer support. It doesn't even offer builds! No, it's the vendors that offer support for their JDK builds.
Java 21 is infinitely better than Java 8. It's technically superior on all fronts. It's faster, more secure, more operations-friendly, more performant and more memory efficient.
Is Java 21 faster than Java 11 : When running compiled code with different versions of the JDK, then the performance can differ. For example, it runs faster and with less memory in Java 21 than Java 11.
Should I upgrade from Java 17 to 21 : Along with thousands of performance, stability and security updates, Java 21 delivers dozens of new features and enhancements, 15 of those enhancements are significant ones(each with its own JEPs), covering six preview features and one incubator feature.
