The ExperimentalFarm class represents crops grown on an experimental farm. An experimental farm is a rectangular tract of land that is divided into a grid of equal$-$sized plots. Each plot in the grid contains one type of crop. The crop yield of each plot is measured in bushels per acre.A farm plot is represented by the Plot class. A partial definition of the Plot class is shown below.public class Plotprivate String cropType; private int cropYield;public Plot $($String crop, int yield$)\{/*$implementation not shown $*/$Bookmarkpublic String getCropType$()$return cropType;public int getCropYield$)$return cropYield;The grid of equal$-$sized plots is represented by a two$-$dimensional array of Plot objects named farmPlots, declared in the ExperimentalFarm class.
