[Java] Assign same value to different variables - trick question incl.

public class PlayGround {
    public static void main(String[] args) {
        int x, y;
        x = y = 9;
        System.out.println(x + " " + y); // prints out 9 9
    }
}

public class PlayGround {
    public static void main(String[] args) {
        int i = 0;
        int[] nums = new int[] { 7, 8 };
        nums[i] = i = 1;
        // What are the values of i & the array nums?
    }
}
