An Item object stores information about one store item.

public class Item
{
    /** Returns the category of this item */
    public String getCategory()
    { /* implementation not shown */ }

    /** Returns the price of this item */
    public int getPrice()
    { /* implementation not shown */ }

    /* There may be instance variables, constructors,
       and methods that are not shown. */
}

A Store object stores a list of Item objects. Complete the countItemsByCategory method so it returns the number of items with the given category.

public class Store
{
    private ArrayList<Item> items;

    /** Returns the number of items whose category
     *  equals targetCategory.
     */
    public int countItemsByCategory(String targetCategory)
    { /* to be implemented */ }
}

item categories	`targetCategory`	returns
`["snack", "drink", "snack", "fruit"]`	`"snack"`	`2`
`["drink", "drink", "snack"]`	`"drink"`	`2`
`["fruit", "snack"]`	`"candy"`	`0`

Complete the countItemsByCategory method.
