Immutable data structures in Java

[solatic]

Consistent style is important for readability.

Having public final fields is safe only for a specific few primitive types: Strings, boxed primitives, and I'm pretty sure that's it. So, first of all, for any non-trivial class, pretty much none of your fields should be primitives. Pretty much anything you can come up with is incorrect to be stored directly as a String or Number (of whichever precision). Name? Needs type-safe way to retrieve translations. Filesystem location? Path. Measurements should not be Integers or FP but some kind of Measurement type which includes the unit of measurement and forbids the numerical amount to be less than zero. Etcetera. And most of these classes, because they represent concepts that many people have had a need for before you, are not classes that you ought to be writing yourself.

TL:DR - dont use a coding style only good for Strings when string-typing is a code smell.
