Demonstrate an understanding of working with bags in Java by implementing a class called ShoppingCart that implements the BagInterfaceMyType in Java. Your implementation should include the following:

Fields:

• MyType[] myBag;
• int numberofProducts;
• Default_Capacity;

Methods:

• Constructor(): initialize bag
• add() – will be used to add a new entry.
• toArray() – provides an array of the allocated bag.
• isFull() – test whether the bag is at the maximum capacity.

Implement a BagDemo that tests your bag implementation class.

Methods:

• testAddl() – will add the contents to the Bag.
• displayBag() – will display the contents of the Bag.

Your deliverables will consist of a zip file with the following:

• The Java source code with all the required classes.
•  Screenshots of your program’s execution and output.
