@Shawn do you mean cryptographic hashing or hashing as in hashcode? If the later then I agree, we need a straightforward way to generate hashes of composite objects which does not require knowing about primary numbers or magic formulas. How about we move to #C0B8Q383C with that?

But for object hashes there's Objects.hash() on the JVM I think.

@karelpeeters I did no know about Objects.hash(), thanks!

[robstoll]

Notice that Objects.hash is slitly slower than an own implementation. But only relevant if you store a lot of objects in a HashSet/Map

[voddan]

@robstoll why slower? Because of the method call?

I don't remember the details but I remember that it was mentioned in effective Java
