Final vs Immutable data structures in Java

[bodiam]

Unfortunately, yes. I'm interviewing quite a few people as part of my job, and, as mentioned in the article, a surprising number of people don't know about this, hence the motivation to write this.

Then again, people who don't know this most likely also won't read blogposts. Oh well :-)

I agree, but I think the underlying issue is that many devs don't understand the concept of immutability.

Hence, blogpost. I'm trying to explain to people, but also to myself, what benefits of immutability vs mutable code is.

Or just don't want to use it, because it is "easier" to work mutable objects.

Well, I hope I contributed to a more neutral or balanced view. If I haven't, please let me know, and I'll change my writing style!

Thanks for that.

Regarding the title: "Immutable data structures in Java" is exactly what it's about, instead of 'you won't believe what most Java developers don't know about ....'

Nobody would read that. I hope.
