By using Java:

Design a Customer class to handle a customer loyalty marketing campaign. After accumulating $100 in purchases, the customer receives a $10 discount on the next purchase.

Record customers name and id.

Provide constructors, mutators, accessors, and methods:

- void makePurchase (double amount).

- boolean discountReached ().

- string toString ().

- boolean equals ().

Provide a demo program and test a scenario in which a costomer has earned a discount and then made over $90, but less than $100 in purchases. This should not result in a second discount. Then add another purchases that results in the second discount.
