Write a method called centroid that takes one formal parameter of type OUPolygon and returns the centroid of the actual parameter as a Point, which is another class in the java.awt library.

Use a for$-$each loop $($see p$\mathrm{.}116$ of Barnes and Kolling$)$ to access each of the polygon$$s points.

Accumulate the total of the x values and the total of the y values of the polygon$$s points.

Once you have the totals, divide each by the number of points to find their means. $($It is preferable to keep decimal places and round to an integer at the end.$)$

Return a Point object whose x and y coordinates are integer approximations of the mean x and y values in the polygon poly.
