Java Records slash a million lines of code off my programs (medium.com)

Advances in the java programming language, version 16 and newer, slashed a million lines of code from my codebase. Maintaining my programs became easier overnight, due to this 1 secret trick: Records.  Unfortunately version 16 was not LTS, so I had to wait until this year's release of version 21, which is LTS.   Go read the linked article. It explains Java Records in a very approachable manner.

I feel like so much effort is spent trying to solve problems that just aren't problems.

Creating simple data objects (or what we used to call Java Beans) is ready to do - especially in a modern IDE. It's also simple to understand what is happening in one and different take very long to read at all.

I can count on the fingers of one hand the number of times I've actually needed to write a hash or equals method.

But the solution to this, in my opinion, non problem is to use a highly inflexible tool that only works in a subset of cases - e.g. when it's ok for your data objects to be immutable.

I can't count on one hand the number of times I've needed to write hashcode/equals in the last week. It's easy to do and records would make it harder to get wrong.
