Hello, this very much depends on the computer language you are using, could you please specify what you mean? – Alex Angel Mar 19 '21 at 15:11

If you are talking about the schematics of the java language in regards to your question, this will help: https://stackoverflow.com/a/32010236/11192546 If you are talking about how the java bytecode interpreter works with [references](https://stackoverflow.com/a/53137643/11192546) and [variables](https://softwareengineering.stackexchange.com/a/322058) then I suggest you read [JVM SE Spec 16 - 2.4. Reference Types and Values](https://docs.oracle.com/javase/specs/jvms/se16/html/jvms-2.html#jvms-2.4), – Alex Angel Mar 19 '21 at 17:21

Thank you! You helped me find the same topic! But their answers are all ‘figures’. I am looking for a more professional answer – 尤春光 Mar 19 '21 at 17:42
