The lifetime of a class and an object. Java is a complete application runtime environment, ie Java applications are designed in such a way so as to run inside a Java Virtual Machine installed in the Mac. Please refer "Inside JVM" book in order to learn more about JVM in detail. Initialization of a class consists of two steps: init its direct super class, it its direct super class hasn't already inited. So there the programming language is Java, but the platform is not a JVM platform. Diagnostic commands are "helper routines inside the JVM" that produce "text output." They can be executed via the jcmd utility (and soon via JMX). With Java RTS, real-time components and non-real-time components can coexist and share data on a single system. Java RTS features are delivered via a separate real-time enabled version of the Java VM. The above information is just very basic guide of what JVM consists of. Inside Java Virtual machine:- as the name suggests it is a virtual machine run as java process which talks to physical machine. Executing the class's class init method, if it has one. The HotSpot represent the block of code executed by JIT compiler. Adam: …another way is this strategy we have around running Java inside of a JavaScript environment.
