Interfaces are Better Utilities (Than Classes) #airhacks #java #short

Interfaces are better suitable for the implementation of "utility"-only functionality.

You can use enums for utility classes. So no class can implement this.

enum Calculator {
;

static int add(int a, int b) {
return a + b;
}
}

is the main reason to write less code? or there are other pro or cons?

Don't know why, but looks wrong to me. Interface -> implement it, thats my thinking.
But of course default methods are a good thing.

we only need fat arrow like typescript to make it more short
