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, [ 4 ] Java SE 23 is the latest version, while versions 21, 17, 11 and 8 are the currently supported long-term support (LTS ...

A Java virtual machine (JVM) is a virtual machine that enables a computer to run Java programs as well as programs written in other languages that are also compiled to Java bytecode. The JVM is detailed by a specification that formally describes what is required in a JVM implementation.
[1] The JVMTI is a native interface of the JVM. A library, written in C or C++, is loaded during the initialization of the JVM. [2] The library has access to the JVM state by calling JVMTI and JNI (Java Native Interface) functions and can register to receive JVMTI events using event handler functions that are called by the JVM when such an ...
The same version of the JVM can be used in OpenJDK 8 and later releases, which means that many features and improvements can be exploited by applications that run on different versions of Java. Compared to Oracle 's HotSpot VM, OpenJ9 touts higher start-up performance and lower memory consumption at a similar overall throughput.
It includes the original 1.0 release, the subsequent 1.5 maintenance release, and as of 2006, the pending 6.0 maintenance release. [ clarify ] Important Web Start features include the ability to automatically download and install a JRE in the case where the user does not have Java installed, and for programmers to specify which JRE version a ...
In software design, the Java Native Interface (JNI) is a foreign function interface programming framework that enables Java code running in a Java virtual machine (JVM) to call and be called by [1] native applications (programs specific to a hardware and operating system platform) and libraries written in other languages such as C, C++ and assembly.
The Java software platform provides a number of features designed for improving the security of Java applications. This includes enforcing runtime constraints through the use of the Java Virtual Machine (JVM), a security manager that sandboxes untrusted code from the rest of the operating system, and a suite of security APIs that Java developers can utilise.
