So I'm interested is there a way to overload operator in Java 8? Is there exist something like
void operator(){ }
in C++?

9No, it still doesn't. And I don't believe it ever will. – fge May 21 '14 at 11:47

3No. User-defined operator overloads are not allowed in Java. – awksp May 21 '14 at 11:47

1No . Any sources for your question? – Santhosh May 21 '14 at 11:47

3No but actually _Why should Java?_ – akash May 21 '14 at 11:50

1@TAsk because C++ can ;) – PKlumpp May 21 '14 at 11:52

2Java's designers are extremely committed to backwards compatibility, so `==` will probably never be overridable. If you allowed other operators to be overridable, that would probably cause even more confusion than there is today (see, e.g., the "why can't I compare strings using `==` question that pops up on SO every so often.) – yshavit May 21 '14 at 11:55

No, there is no operator overloading in Java 8. If you don't know it yet, you could have a look at Xtend which is a JVM language that compiles to pure Java. It supports operator overloading and a lot more features while it's still has a static type system.
(And, of course, there is Groovy, Scala, and other JVM scripting languages which support operator overloading as well).
