Ever wondered how Java works behind the scenes? Learn how JVM, Class Loader, Bytecode, Interpreter & JIT Compiler execute your Java program step by step. Clear diagram + simple explanation.
Ever wondered what happens behind the scenes when you run a Java program?
Let’s find out:
Java (JVM Runtime):
Java source code (.java) is compiled into .class bytecode using javac.
The Class Loader loads bytecode into the Java Runtime Environment (JVM).
Bytecode is verified and executed.
JVM uses both an Interpreter and a JIT Compiler; frequently used code (hot paths) is converted into native machine code, making Java faster.
