java maximum value of int

From java documentation int has a minimum value of -2,147,483,648 and a maximum value of 2,147,483,647 (inclusive).

I have a class Test.java.

public class Test
{
    public static void main(String[] args)
    {
        int i=2147483647; //max positive value an int can store
        for(;;)
        {
            System.out.println(++i);
        }
    }
}

As per my knowledge ++i should increment the value of i by 1 and throw exception, because 2147483648 is not allowed in int.

But when I run above program it goes running(because of infinite loop), and instead of incrementing the value to 2147483648, the value assigned to i is -2147483648, And values is decremented each time by 1.

Sample run (after modifying class)

public static void main(String[] args)
{
    int i=2147483647;
    for(;;)
    {
        System.out.println(++i);
        System.out.println(++i);
        System.out.println(++i);
        System.out.println(++i);
        System.out.println(++i);
        break;
    }
}

Output:

-2147483648
-2147483647
-2147483646
-2147483645
-2147483644

Answers/Hints will be appreciated.
