You need to write a class called SingleItemBox (in a file called SingleItemBox.java that you create). This class has a constructor that takes a single item (of any type) and puts it in the box. You also need a method called getItem() which provides the item back to the user but does not remove it from the box (this is an accessor, if you remember, sometimes called a getter). Make sure to comment your code as you go in proper JavaDoc style. Please implement this code using generics concept in java.
