Abbreviation for Java virtual machine.

Java Virtual Machine*. The part of the Java Runtime Environment responsible for interpreting bytecodes.

Java Virtual Machine. A software execution engine that safely and compatibly executes the byte-codes in Java class files on a microprocessor (whether in a computer or in another electronic device).

Java HotSpot performance engine - the ultra-high-performance engine for a Java runtime environment which features an adaptive compiler that dynamically optimizes the performance of running applications.

KJava virtual machine - the small-footprint, highly optimized foundation of a runtime environment within the Java 2 Platform, Micro Edition. Derived from the Java virtual machine, it is targeted at small connected devices and can scale from 30KB to approximately 128KB, depending on the target device's functionality.

Java Card Virtual Machine - an ultra-small-footprint, highly-optimized foundation of a runtime environmentwithin the Java 2 Platform, Micro Edition. Derived from the Java virtual machine, it is targeted at smart cards and other severely memory-constrained devices and can run in devices with memory as small as 24K of ROM, 16K of EEPROM, and 512 bytes of RAM.
