+- isn't a single operator. It's the binary plus followed by the unary negation operator.

C= 0 ?? WHY ??

There is no C in your example. Java is case sensitive. If you meant c, then its value is 1.

thanks Bear Bibeault !

but i didn't understand, i guest i will have to read more about it .. anyway thanks again !

[podonga poron]

now i understand it

int a = 5;
int b = 2;
int c = a+-b;

c = 3;

because

5+-2
5+(-2)
5-2
3

i leave this resolved for someone that have the same doubt ...
