The applications scripted in other languages, i.e. The native procedures used in the applications are part of the Native Method Stack. To be precise, it is similar to stack but used for native methods. Therefore, it is a key component of Java Architecture. Java Virtual Machine (JVM) is a engine that provides runtime environment to drive the Java Code or applications. The JVM might be a virtual machine that executes Java bytecode, but somewhere, it itself has to be coded in something. jvm.go - A toy JVM written in Go - Find best open source In this chapter, we will cover the following topics related to alternative JVM languages: Understanding why should we choose a language other than Java for JVM development.
