How JVM Works – JVM Architecture

JVM(Java Virtual Machine) runs Java applications as a run-time engine. JVM is the one that calls the main method present in a Java code. JVM is a part of JRE(Java Runtime Environment).

Java applications are called WORA (Write Once Run Anywhere). This means a programmer can develop Java code on one system and expect it to run on any other Java-enabled system without any adjustment. This is all possible because of JVM.

When we compile a .java file, .class files(contains byte-code) with the same class names present in .java file are generated by the Java compiler. This .class file goes into various steps when we run it. These steps together describe the whole JVM. 

Understanding the Java Virtual Machine (JVM) is essential for writing efficient code. For a more detailed look at the internal workings of the JVM, including memory management and performance optimization, the Java Programming Course offers in-depth insights into JVM architecture.
