What is a JVM instruction?

Question

So I was talking to somebody who runs Interviews (your standard HR manager) about what they really look for in an interview, and he mentioned something (among many other things) about testing for JVM Instruction knowledge.

I didn't know what those were, but I thought he was talking about bytecode instructions.

I have done some research and it seems that I can't find anything on "JVM Instructions", all I find are references to bytecode instructions, which I already knew about.

For example: http://docs.oracle.com/javase/specs/jvms/se7/html/jvms-6.html at first seems to talk about JVM Instructions, but that seems to be what I know of as bytecode instructions.

So my question is, are there such thing as JVM Instructions that are separate from bytecode instructions, or are they one and the same?

Thanks

Answer 1

So my question is, are there such thing as JVM Instructions that are separate from bytecode instructions, or they one and the same?

They are one and the same.

Answer 2

He's most likely just talking about bytecode instructions, as that's what the JVM runs.
