Java Architecture

What is Java Architecture?

Here, I will explain you the java architecture in simple steps.

• In Java, there is a process of compilation and interpretation.
• The code written in Java, is converted into byte codes which is done by the Java Compiler.
• The byte codes, then are converted into machine code by the JVM.
• The Machine code is executed directly by the machine.

Components of Java Architecture

There are three main components of Java language: JVM, JRE, and JDK.

Java Virtual Machine, Java Runtime Environment and Java Development Kit respectively.

Let me elaborate each one of them one by one:

Java Virtual Machine:

Ever heard about WORA? (Write once Run Anywhere).  Well, Java applications are called WORA because of their ability to run a code on any platform. This is done only because of JVM. The JVM is a Java platform component that provides an environment for executing Java programs. JVM interprets the bytecode into machine code which is executed in the machine in which the Java program runs.

So, in a nutshell, JVM performs the following functions:
