Description: During the development process, Java source code is compiled into a special format called bytecode by the Javac compiler found in the Java Development Kit (JDK). This bytecode can be executed by the JVM and is saved with a .class extension.

Definition: The JVM is a critical component in the world of Java programming. It serves two primary functions: enabling Java applications to run across various devices and operating systems (the "Write once, run anywhere" principle) and efficiently managing and optimizing program memory. Technical D
