The Java language has undergone several changes since JDK 1.0 as well as a number of additions of classes and packages to the standard library. Since J2SE 1.4, the evolution of the Java language has been governed by the Java Community Process (JCP), which uses Java Specification Requests (JSRs) to propose and specify additions and changes to the Java platform. The language is specified by the Java Language Specification (JLS); changes to the JLS are managed under JSR 901. In September 2017, Mark Reinhold, chief architect of the Java Platform, proposed to change the release train to "one feature release every six months" rather than the then-current two-year schedule. This proposal took effect for all following versions, and is still the current release schedule.
In addition to the language changes, other changes have been made to the Java Class Library over the years, which has grown from a few hundred classes in JDK 1.0 to over three thousand in J2SE 5. Entire new APIs, such as Swing and Java2D, have been introduced, and a number of the original JDK 1.0 classes and methods have been deprecated, and very few APIs have been removed (at least one, for threading, in Java 22). Some programs allow the conversion of Java programs from one version of the Java platform to an older one (for example Java 5.0 backported to 1.4) (see Java backporting tools).
Regarding Oracle's Java SE support roadmap, Java SE 25 (LTS) is the latest version as of September 2025 (and Java 26 a later released version) while versions 21, 17, 11 and 8 are the other still supported (long-term support − LTS) versions, where Oracle customers will receive Oracle Premier Support. Oracle continues to release no-cost public Java 8 updates for development and personal use indefinitely.
In the case of OpenJDK, both commercial long-term support and free software updates are available from multiple organizations in the broader community.
Java 27 was released on 15 September 2026 and Java 25 LTS was released on 16 September 2025.

| Released | 8 December 1998 (27 years ago) (1998-12-08) |
The release on December 8, 1998 and subsequent releases through J2SE 5.0 were rebranded retrospectively Java 2 and the version name "J2SE" (Java 2 Platform, Standard Edition) replaced JDK to distinguish the base platform from J2EE (Java 2 Platform, Enterprise Edition) and J2ME (Java 2 Platform, Micro Edition). This was a significant release of Java as it tripled the size of the Java platform to 1520 classes in 59 packages. Major additions included:
| Codename | Kestrel |
|---|---|
| Released | 8 May 2000 (26 years ago) (2000-05-08) |
The most notable changes in the May 8, 2000 release were:

| Public | October 2008 (2008-10) |
| Paid | February 2013 (2013-02) |
The February 6, 2002 release was the first release of the Java platform developed under the Java Community Process as JSR 59. Major changes included:
Public support and security updates for Java 1.4 ended in October 2008. Paid security updates for Oracle customers ended in February 2013.
Java 6 can be installed to Mac OS X 10.5 (Leopard) running on 64-bit (Core 2 Duo and higher) processor machines. Java 6 is also supported by both 32-bit and 64-bit machines running Mac OS X 10.6 (Snow Leopard).
Java 6 reached the end of its supported life in February 2013, at which time all public updates, including security updates, were scheduled to be stopped. Oracle released two more updates to Java 6 in March and April 2013, which patched some security vulnerabilities.
After Java 6 release, Sun, and later Oracle, released several updates which, while not changing any public API, enhanced end-user usability or fixed bugs.

Java 7 was the default version to download on java.com from April 2012 until Java 8 was released. Java 7 updateseditOracle issued public updates to the Java 7 family on a quarterly basis until April 2015 when the product reached the end of its public availability. Further updates for JDK 7, which continued until July 2022, are only made available to customers with a support contract.

Java 8 was released on 18 March 2014, and included some features that were planned for Java 7 but later deferred.
Work on features was organized in terms of JDK Enhancement Proposals (JEPs).
Java 8 is not supported on Windows XP but as of JDK 8 update 25, it can still be installed and run under Windows XP. Previous updates of JDK 8 could be run under XP by downloading archived zip format file and unzipping it for the executable. The last version of Java 8 that could run on XP is update 251.
From October 2014, Java 8 was the default version to download (and then again the download replacing Java 9) from the official website. "Oracle will continue to provide Public Updates and auto updates of Java SE 8, Indefinitely for Personal Users".

Java SE 9 was made available on September 21, 2017 due to controversial acceptance of the current implementation of Project Jigsaw by Java Executive Committee which led Oracle to fix some open issues and concerns and to refine some critical technical questions. In the last days of June 2017, Java Community Process expressed nearly unanimous consensus on the proposed Module System scheme.
The first Java 9 release candidate was released on August 9, 2017. The first stable release of Java 9 was on September 21, 2017.
At JavaOne 2011, Oracle discussed features they hoped to release for Java 9 in 2016. Java 9 should include better support for multi-gigabyte heaps, better native code integration, a different default garbage collector (G1, for "shorter response times") and a self-tuning JVM. In early 2016, the release of Java 9 was rescheduled for March 2017 and later again postponed four more months to July 2017.

The preview feature JEP 325 extends the switch statement so it can also be used as an expression, and adds a new form of case label where the right hand side is an expression. No break statement is needed. For complex expressions a yield statement can be used. This becomes standard in Java SE 14.

The Java implementation itself was and is still written in C++, while as of Java 16, more recent C++14 (but still not e.g. C++17 or C++20) is allowed. The code was also moved to GitHub, dropping Mercurial as the source control system.

The following JEPs were targeted to this release of Java SE:
Java 26 removes support for creating Java applets with the Applet API, after having been deprecated since the release of Java 17 in September 2021.
The specification for Java 27 was finalized in August 2026, with 9 JEPs making it into the release. It was released on September 15, 2026.
The following JEPs were targeted to this release of Java SE:
Java 27 removes several outdated key exchange algorithms from default security providers. It also removes legacy object header formats when running on supported platforms. It deprecates non-compact object headers, non-hybrid TLS key exchange algorithms, and old APIs related to PEM parsing.
The officially supported Java platform, first developed at Sun and now stewarded by Oracle, is Java SE. Releases are based on the OpenJDK project, a free and open-source project with an open development model. Other Java implementations exist, however—in part due to Java's early history as proprietary software. In contrast, some implementations were created to offer some benefits over the standard implementation, often the result of some area of academic or corporate-sponsored research. A number of Linux distributions include builds of OpenJDK through the IcedTea project started by Red Hat, which provides a more straightforward build and integration environment.
Visual J++ and the Microsoft Java Virtual Machine were created as incompatible implementations. After the Sun v. Microsoft lawsuit, Microsoft abandoned it and began work on the .NET platform. In 2021, Microsoft started distributing compatible "Microsoft Build of OpenJDK" for Java 11 first then also for Java 17. Their builds support not only Windows, but also Linux and macOS.
Other proprietary Java implementations are available, such as Azul's Zing. Azul offers certified open source OpenJDK builds under the Zulu moniker.
Prior to the release of OpenJDK, while Sun's implementation was still proprietary, the GNU Classpath project was created to provide a free and open-source implementation of the Java platform. Since the release of JDK 7, when OpenJDK became the official reference implementation, the original motivation for the GNU Classpath project almost completely disappeared, and its last release was in 2012.
The Apache Harmony project was started shortly before the release of OpenJDK. After Sun's initial source code release, the Harmony project continued, working to provide an implementation under a lax license, in contrast to the protective license chosen for OpenJDK. Google later developed Android and released it under a lax license. Android incorporated parts of the Harmony project, supplemented with Google's own Dalvik virtual machine and ART. Apache Harmony has since been retired, and Google has switched its Harmony components with equivalent ones from OpenJDK.
Both Jikes and Jikes RVM are open-source research projects that IBM developed.
Several other implementations exist that started as proprietary software, but are now open source. IBM initially developed OpenJ9 as the proprietary J9, but has since relicensed the project and donated it to the Eclipse Foundation. JRockit is a proprietary implementation that was acquired by Oracle and incorporated into subsequent OpenJDK versions.
Amazon developed Corretto, a no-cost, multiplatform, production-ready distribution of OpenJDK with long-term support that includes performance enhancements and security fixes. Corretto is certified as compatible with the Java SE standard and is used internally at Amazon for a number of production services.
The Eclipse Temurin project, formerly known as AdoptOpenJDK, provides prebuilt OpenJDK binaries from a fully open source build farm. The project transitioned to the Eclipse Foundation in 2021 as part of the Adoptium Working Group, which ensures high-quality, vendor-neutral Java runtime distributions.
BellSoft Liberica JDK is another OpenJDK-based implementation that provides builds for a wide range of platforms, including support for embedded systems and older architectures. It offers both standard and "Full" versions that include additional components like JavaFX.
SAP Machine is SAP's downstream distribution of OpenJDK, optimized for SAP applications and deployments. It provides both short-term and long-term support releases aligned with OpenJDK's release schedule.
Alibaba Dragonwell is a downstream version of OpenJDK with some in-house optimizations. It includes enhancements in startup performance, footprint, and throughput.
GraalVM represents a significant departure from traditional Java implementations. Developed by Oracle Labs, it provides a polyglot virtual machine supporting multiple languages beyond Java, including JavaScript, Python, Ruby, and R. GraalVM includes an advanced just-in-time compiler written in Java and supports ahead-of-time compilation for creating native executables, substantially reducing startup time and memory footprint.
The Red Hat build of OpenJDK is Red Hat's supported distribution of OpenJDK for Red Hat Enterprise Linux and Windows, providing long-term support and regular updates as part of Red Hat's subscription offerings.
The Semeru Runtime, based on the Eclipse OpenJ9 JVM and OpenJDK class libraries, is IBM's no-cost Java runtime optimized for cloud deployments. It offers improved startup time, smaller memory footprint, and better throughput compared to HotSpot-based implementations.
