Since the Method and Heap areas share memory for multiple threads, the data stored is not thread-safe.

and initializes the class file when it refers to a class for the first time at runtime, not compile time. Java's dynamic class loading functionality is handled by the ClassLoader subsystem. JVM Architecture DiagramĪs shown in the above architecture diagram, the JVM is divided into three main subsystems: Below is a diagram of the Architecture of the JVM. class file is input into the JVM, which loads and executes the class file. The compiler compiles the Java file into a Java. Java was developed with the concept of WORA ( Write Once Run Anywhere), which runs on a VM.

What Is the JVM?Ī Virtual Machine is a software implementation of a physical machine. In this article, we will learn more deeply about the JVM architecture in Java and different components of the JVM. It is very important, as a developer, that we know the architecture of the JVM, as it enables us to write code more efficiently. 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. Every Java developer knows that bytecode will be executed by the JRE (Java Runtime Environment).
