Java simple arrays structure in memory

Question

How Java stores objects like int[] in memory, what is they structure?

Not complex compound types like ArrayList - the question is not about them. I want to know exactly about arrays of primitive types like a int[].

Can't find any detailed information on this, other than that these are just chunks of memory. Although there is a whole structure - pointers and so on ...

Thanks a lot,

That's going to depend on the particular implementation. The most common is probably a C style pointer with some metadata (like size), but that shouldn't matter to anyone writing a program in Java- those kind of details aren't exposed in any way. — Gabe Sechan

Thanks. My question for in-depth understanding and study of details. — Topin Gudot

The hotspot source code is on GitHub. If you want to know implementation details - and this goes for anything, not just the JVM - then you should be prepared for the fact that you might have to go and look yourself. There is a good reason that low-level implementation details aren't well-documented and that's because they quickly become outdated. As a rule of thumb, if you don't know where to begin looking for an implementation detail, you probably don't have a good enough reason to not know or care about it. — Michael
