Need a java code
Create a class called SingleItem
This class represents a bag that can hold any single type of object (decided at bag-creation time), and only one item of that type at a time. You may have a zero-parameter constructor if you want one, but you must have the following three features:
Add a method called (addItem()) which returns whether or not it was successfully added
Add a method which removes an item from the bag and returns it (deleteAnItem()), return null if there is no item
Add a method to check if an item is in the bag (hasAnIteminTheBag()) which returns true or false
Each object that is created from a class is called a(n) __________ of the class. a. reference b. example c. instance d. event
