What Are JVM And Its Architecture?
Java applications run the JVM (Java Virtual Machine) as a runtime engine. The primary method contained in a Java programme is called the JVM. JRE includes JVM (Java Runtime Environment).JVM’s full form is Java Virtual Machine.
WORA refers to Java programmes (Write Once Run Anywhere). As a result, a programmer can create Java code on one system and expect it to function correctly on any other Java-enabled device. JVM makes all of this possible. To learn more about java, join the Best Java Training Institute in Chennai at FITA Academy.
JVM Architecture:
Let’s grasp the JVM architecture now in this blog. The Java Virtual Machine (JVM) architecture includes a classloader, memory space, execution engine, etc. The JVM Architecture in java has the following components:
1)Class Loader
A part of the system which loads class files is the class loader. It carries out the three main tasks of loading, linking, and initialization.
2)Method Area
Metadata, the constant runtime pool, and method code are all stored in the JVM Method Area and other class structures.
3)Heap
The heap contains every object, along with any associated instance variables and arrays. This memory is shared by numerous threads and is universal.
4)JVM Language Stack
Local variables and their partial results are kept in Java language stacks. Each thread has a different JVM stack built simultaneously with the line itself. Every time a method is executed, a new frame is formed and removed once the technique has been called. To learn more about the JVM language stack, join the Best Java Course Online.
5)PC Registers
The address of the Java virtual machine instruction that is now running is stored in the PC register. Each thread in Java has a unique PC register.
6)Native Method Stacks
The instructions of native code are stored in native method stacks, which depend on the native Library. Instead of Java, some other programming language was used to write it.
7)Execution Engine
It is a sort of software that is used to test hardware, programmes, or entire systems. The test execution engine never carries any data about the tested product.
8)Native Method Interface
A programming framework is the Native Method Interface. It enables libraries and native programmes to call Java code executed in a JVM.
9)Native Method Library
Native Library is a collection of the Native Libraries (C, C++) that the Execution Engine requires.
