Is operator overloading possible in java?

Question

does java support operation overloading concept?please help with an example

Answer 1

Yes, it's possible. If you need it, you should have to explain WHY you want to to a friend, and make sure that they agree that you need it prior to doing it, since it's generally a bad idea in Javar.

Answer 2

yes possible,

On the other hand, if you've ever tried to make a nice matrix Class, you realize why operator overloading is so useful. Having the option available means you are able to apply a more natural coding style when it applies. Further, I have seen far too many unintuitive method and variable names to accept this argument.

To continue my point, having to write something like

u = v1.add(v2);

to add two vectors (as used in Physics, i.e. magnitude and direction) is much more awkward than

u = v1 + v2;

in this context, since this style of infix mathematical notation is the most natural for the problem domain of Physics.

I agree that I wouldn't be as happy programming Java without the String concatenation operator. However, my argument for consistency would be in support of a general operator overloading mechanism rather than elimination of String concatenation.

Answer 3

yes operator overloading in java is possible but thats not suggested unless you explicity need the thing
