Why doesn't Java need Operator Overloading? [closed]

Question

Why doesn't Java need operator overloading? Is there any way it can be supported in Java?

Answer 1

Java only allows arithmetic operations on elementary numeric types. It's a mixed blessing, because although it's convenient to define operators on other types (like complex numbers, vectors etc), there are always implementation-dependent idiosyncrasies. So operators don't always do what you expect them to do. By avoiding operator overloading, it's more transparent which function is called when. A wise design move in some people's eyes.

Answer 2

Java doesn't "need" operator overloading, because no language needs it.

a + b is just "syntactic sugar" for a.Add(b) (actually, some would argue that a.Add(b) is just syntactic sugar for Add(a,b))
