good equals implementation?:)

[final cliff]

I uploaded your attachments as Gist.

@main beacon I don't understand what this class is about
The names sound like chess but the way the class is done, it doesn't sound like a chess engine

Sound correct
By the way, don't forget to put final on everything that cannot change
And don't use clonable

[main beacon]

ok, thank you very much 🙂

IntelliJ will generate them for you. Just click on a class, generate and then Equals and Hashcode

Same with toString

don’t waste your time implementing them yourself

the compiler can always do it better

[graceful stag]

Thats not true

It depends on the situation

[vague schooner]

yeah, the compiler is good at handling most situations, it gives a good distribution for general case. but it doesnt always do it better, based on the situation

[fathom carbon]

sure but I’ve never run into a case where I could make a better equals and hashcode function than intelliJ

[vague schooner]

its a good tool, if you cant use records or lombok

[quaint sage]

The IDE couldn't implement the hashcode and equals for a new List implementation.

It can implement most cases where there is no family-of-types relationship, and where there is no internal caching or other stateful-ness that does not reflect external state.
