Design and implement Java program as follows:

1. There will be a Snack class with following attributes: id (combination of numbers and letters), size (values S, M, or L), and price
2. There will be two child classes FruitSnack and SaltySnack with the following additional

attributes:

• FruitSnack: It includes citrus fruit indication (value of thisvariable of is true or false)
• SaltySnack: It includes nut snack indication (value of this variable ofis true or false)

 

1. The Snack class hierarchy must provide the following functionality:

• On creation, a snack instance must be given all attribute values except its price, which must be calculated
• Price iscalculated as follows:
  • There is a flat fee of $19.99 for S snack, $29.99 for M snack, and $39.99 for L snack.
  • FruitSnack has an additional fee of $5.99 when it has a citrus fruit. Please add only a single citrus fruit, and no preventing coding isrequired to limit addingmore than one.
  • SaltySnack has an additional fee of $4.50 when it has a nut snack. Please add

only a single nut snack no preventing coding is required tolimit adding more than one.

• Each class must have a method to return or display the class's values to the console

 

1. Implement OrderSystem class with main method with following functionality:
   • Order asnack and after ordering it will display the snack type, its size, id and price
   • Exit program

 

1. Your classes must be coded with correct encapsulation: private/protected attributes, get methods, and set methods
2. There should be appropriate overloading and overriding methods
3. OrderSystem should take advantage ofthe inheritance properties (e.g., use Snack variable regardless which snack instance as appropriate)
4. The prices for S, M, L, citrus fruit, nut snack can be hardcoded in the program.
