Java primitive declaratiron
Given the following code snippet:
int i = 0; int y = + ++i; System.out.println(y);
The result is 1. Why is this a valid declaration? Can anyone explain what is =+?
int y = + ++i;
The first + in this line is simply the unary + operator (see: Assignment, Arithmetic, and Unary Operators). It does nothing. It's similar to the unary - operator. The line above is equivalent to:
int y = ++i;
which increments i and then assigns the new value of i to y.
