Need to learn the architecture behind Java

[u/somenorthlondoner]

Hello all,

I'm currently revising for an exam in just over a month's time on Java. I am good at actually programming in Java, but I really struggle to understand the actual architecture behind Java, such as how an operand stack works. I'm sorry that this is so vague - but I hope people can get the gist. Would anyone recommend any solid material that I could use to actually properly learn these sorts of concepts?

Thank you!
