JVM Literally Reads .java Files

The Java Virtual Machine (JVM) is designed to interpret bytecode from Java source code.

However, there's an interesting aspect to consider when the JVM literally reads .java files.

In reality, the JVM does not execute the actual Java code directly. Instead, it loads the bytecode into memory and executes it using its internal execution engine.

This means that the JVM itself is responsible for interpreting the bytecode, which is compiled from the original Java source code.

When you run a Java application, the JVM reads the .class files, which contain the compiled bytecode, and then executes them.

So, the JVM's role is to take the original Java code, compile it into bytecode, and then execute that bytecode on behalf of the user.

Therefore, the JVM is not "reading" the .java files in the traditional sense; instead, it's interpreting the compiled bytecode.

            public class HelloWorld {
                public static void main(String[] args) {
                    System.out.println("Hello, World!");
                }
            }
