The joke is even funnier on my client

Yes, it blends in with Voyager's UI because it's a screenshot of Voyager's UI.

You're using Java, there's your problem

[–] LodeMike@lemmy.today 6 points 5 months ago (1 children)

This syntax isn't actually a problem by itself. Go does this too (no operator overloading)

[–] Gremour@lemmy.world 3 points 5 months ago* (last edited 5 months ago) (1 children)

In Go you can compare structure instances with == (by value). You can also compare pointers (in which case they can be different even if values are equal). You get what you ask for.

Also, I've never needed "Equals" method in Go.

[–] LodeMike@lemmy.today 5 points 5 months ago

I think you can also == two structs in Java, but not classes.

Is there ever an instance when you do want to compare object identity instead of “equal”-ness? I find this behaviour just confusing for beginners and not useful for experts.

[–] calcopiritus@lemmy.world 5 points 5 months ago (1 children)

There are use cases. Like containers where the pointer to the object itself is the key (for example a set). But they are niche and should be implemented by the standard library anyway. One of the things I hate most about Java is .equals() on strings. 99.999% of times you compare strings, you want to compare the contents, yet there is a reserved operator to do the wrong comparison.

[–] marcos@lemmy.world 1 points 5 months ago

Java has the hash interface for using in containers. You don't need to override equality for it.

[–] expr@programming.dev 5 points 5 months ago

99.99% of the time you want to compare by value, which is why languages defaulting to comparing by reference is a stupid default.

[–] Redkey@programming.dev 3 points 5 months ago

Not to take away from your very good point, but I think the word you might be looking for is "eqivalence".

Maybe if you have to check if the object is one you already hold a lock for or account for some similar consequence of questionable architecture.

Where's the original post?

[–] ZILtoid1991@lemmy.world 8 points 5 months ago (2 children)

No longer on the internet, due to the OP's instance is now defunct.

[–] yaroto98@lemmy.world 5 points 5 months ago (1 children)

It was probably on AWS

[–] ChaoticNeutralCzech@feddit.org 6 points 5 months ago

OP's website makmarian.com still works despite all the == usage

[–] ChaoticNeutralCzech@feddit.org 3 points 5 months ago

Not really true, instances that were around to federate with kbin.social have a copy, even a preview image (see my other comment).
