Operators

[Albertina Gonzalez]

Hi,
I have a question about this ...
int x =10++11;
I say, that this is a invalid statement, because the operator is applicated over the variable...
What do you know?

Compile it and see - you'll find that this does not compile as the ++ operator has no variable to operate upon.

if it's written as :
1) int x = 10+ +11;
It works ,the o/p is 21.
2)int x = 10 + +11;
It works ,the o/p is 21.

Is the positioning of space so important,pl.help clarify.

In this case, the space makes little difference as to where it is. The only thing that matters is that there is a space between the '+' signs. If they're together, they represent the increment operator in Java. If they're separate, they represent the addition operator.

This may be helpful JLS 3.2

The longest possible translation is used at each step, even if the result does not ultimately make a correct program while another lexical translation would. Thus the input characters a--b are tokenized (�3.5) as a, --, b, which is not part of any grammatically correct program, even though the tokenization a, -, -, b could be part of a grammatically correct program.
