Java Platform, Standard Edition 7 ReferenceImplementations

Sun Microsystems released the first public implementation as Java 1.0 in 1996.[26] It promised write once, run anywhere (WORA) functionality, providing no-cost run-times on popular platforms. Fairly secure and featuring configurable security, it allowed network- and file-access restrictions. Major web browsers soon incorporated the ability to run Java applets within web pages, and Java quickly became popular.

• “Instead of wasting time and money, we have been able to reduce overall costs by managing our Java estate with Oracle Java SE Subscription. This gives us a huge cost saving opportunity that significantly reduces our IT OPEX bills.”
• In addition to enabling more efficient code, certain runtime exceptions are prevented from occurring, by issuing compile-time errors.
• Either the container operates on all subtypes of a class or interface, usually Object, or a different container class has to be created for each contained class.

Java 8, 11, and 17 are previous LTS versions still officially supported. This release also contains fixes for security vulnerabilities described in the Oracle Critical Patch Update. The JDK implementation of TLS 1.2 now uses a default Diffie Hellman keysize of 2048 bits when a TLS_DHE cipher suite is negotiated and either the client or server does not support FFDHE, which can negotiate a stronger keysize.

Java™ SE Development Kit 8, Update 391 Enterprise Performance Pack (JDK 8u391-PERF)

Bug Database enables you to file your own bug reports, add comments to existing bug reports, and vote for the bugs you consider most important. Standard libraries provide a generic way to access host-specific features such as graphics, threading, and networking. The classes in the Java APIs are organized into separate groups called packages. Each package contains a set of related interfaces, classes, subpackages and exceptions.

Store and update multiple applications on a single, resource-constrained device. Take advantage of the high-performance JDK with advanced optimizations that improve Java application performance and microservices deployment—on-premises and in the cloud. Together, the two technologies add value for cloud native deployments with native image and multilanguage support.

GraalVM for JDK 21 will receive updates under the GFTC, until September 2026, a year after the release of the next LTS. Subsequent updates of GraalVM for JDK 21 will be licensed under the GraalVM OTN License Including License for Early Adopter Versions (GOTN) and production use beyond the limited free grants of the GraalVM OTN license will require a fee.

As a workaround, users can revert to the previous size by setting the jdk.tls.ephemeralDHKeySize system property to 1024 (at their own risk). In JDK 12, two new token options for the java.security.manager system property, “allow” and “disallow”, were introduced. The Oracle JDK Debian package configures storage for Java Preferences API in the /etc/.java/.systemPrefs directory. The -XshowSettings launcher option has been enhanced to print the tzdata version configured with the JDK. The tzdata version is displayed as part of the locale showSettings option.

The Java launcher launches Java by loading a given class (specified on the command line or as an attribute in a JAR) and starting its public static void main(String[]) method. The String[] args parameter is an array of String objects containing any arguments passed to the class. It is simply the name of the method the Java launcher calls to pass control to the program. Java classes that run in managed environments such as applets and Enterprise JavaBeans do not use or need a main() method. A Java program may contain multiple classes that have main methods, which means that the VM needs to be explicitly told which class to launch from. The JDK is a development environment for building applications using the Java programming language.
