In Java 3 = 12 - Hackdot

I really don't think this should be confusing - having a decent grasp on associativity and precedence is a pretty useful skill - so for example understanding WHY println(3 * 2 + "-" + 6 * 3) behaves "differently" is something I'd hope people would get.

And let's be honest, you definitely don't want to 'fix' this by tweaking precedence to include types. That way madness lies. ;)

Definite shout to ubernostrum's commment though - perhaps the confusing thing is that string concatenation is +, but a world of explicit Appends seems horrid, and that ship has very much sailed.

Just be (maybe) glad java doesn't allow generalised operator overloading ;)

I think + for append is fine, it certainly seems to make sense to me that you get "helloworld" from "hello"+"world".

I think the confusing thing is the type coercion. Does it make sense that "2"+3 is "23" but 2+"3" is not 5?

    (3*4).toString() + "=" + 3.toString() + 4.toString())

would not be as surprising that the two sides are different.

In Ada the (String) concatenation operator is '&' (and of course, no implicit promotion to String there, you'll have to use your_type'Image(your_var) or with GNAT your_var'Img).
