Java - How do you find the memory location of each element in a linkedlist?

There's an interview question that asks you to determine if two linkedlists intersect with each other. So we're required to access the memory location of each node/element of the linkedlist since we're comparing the memory location of each node.

Usually we compare the value of each element. However I'm not sure how to access the memory location of such linkedlist element?

Thanks for your advice!

there's `==` operator for that (for reference types) – Victor Sorokin Sep 07 '16 at 16:14

Were you explicitly told that you need to consider the memory locations, or did you decide that requirement by yourself? – Kayaman Sep 07 '16 at 16:31
You don't need the memory location, only the reference values. – Peter Lawrey Sep 07 '16 at 18:24
@PeterLawrey Yes the hints say find and compare the reference values. But I'm not entirely sure what this reference value mean or how to find it? Thanks! – Mandy Sep 09 '16 at 13:38
In java you have two types of fields, primitives like `1` and `2.34` and references. If it's not a primitive value is a reference. You can compare them using `==` – Peter Lawrey Sep 09 '16 at 13:52
