JVM Architecture – Understanding JVM Internals Every Java developer knows that bytecode will be executed by JRE (Java Runtime Environment). But many don’t know the fact that JRE is the implementation of Java Virtual Machine (JVM), which analyzes the bytecode, interprets the code and executes it. It is very important as a developer we should know the Architecture of JVM, this enables us to write code more efficiently. In this JVM architecture in Java with diagram article, we will learn more deeply about JVM architecture in Java and different components of a JVM. What is a JVM in Java? A Virtual Machine is a Software implementation of a Physical Machine, Java was developed with the concept of WORA ( Write Once Run Anywhere ) which runs on a VM. The compiler will be compiling the java file into a java .class file. The .class file is input to JVM which Loads and executes the class file. Below goes the Architecture of JVM.
