JVM Internals: JVM Opcodes and Java ClassFile Explained

In this deep dive, we break down the JVM ClassFile structure and uncover the real instructions that power your Java code — the opcodes.

We’ll walk through:
1) How .class files are structured internally
2) What opcodes are and how the JVM uses them
3) The general format of JVM instructions
4) Common opcodes like aload_0, invokevirtual, iadd, and more

🔥 Stay tuned for upcoming deep dive sessions where we'll analyze real-world bytecode in detail.
