Java primitive declaratiron

Given the following code snippet:

int i = 0;

int y = + ++i;


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.
