This question uses two classes: an Item class that represents an item that has a name and value and an ItemGrid

class that manages a two$-$dimensional array of items. A definition of the Item class is shown below.

public class Item

$\{$

private String name;

private int value;

public Item$($String itemName, int itemValue$)$

$\{$

name $=$ itemName;

value $=$ itemValue;

$\}$

public String getName$()$

$\{$

return name;

$\}$

public int getValue$()$

$\{$

return value;

$\}$

$\}$

The ItemGrid class below uses the two$-$dimensional array grid to represent a group of Item objects.

public class ItemGrid

$\{$

private Item$[][]$ grid;

$//$ Constructor not shown

$/**$ Returns true if xPos is a valid row index and yPos is a valid

$*$ column index and returns false otherwise.
