Write Four java programs (Snack.java, FruitSnack.java, SaltySnack.java, and OrderSystem.java. A Word document that includes a test table with test case #, input, expected output, actual output, and pass/fail columns. There should be at least 3 test cases. Make sure to include test cases that validate data. Include a screen capture of running each test case. Include header comments that include your name, date, and description of the program. Include body comments. (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: o FruitSnack: It includes citrus fruit indication (value of this variable of is true or false) o SaltySnack: It includes nut snack indication (value of this variable of is true or false) (3) 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 is calculated as follows: o There is a flat fee of $19.99 for S snack, $29.99 for M snack, and $39.99 for L snack. o 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 is required to limit adding more than one. o 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 to limit adding more than one. • Each class must have a method to return or display the class’s values to the console. (4) Implement OrderSystem class with main method with following functionality: • Order a snack and after ordering it will display the snack type, its size, id and price. • Exit program. (5) Your classes must be coded with correct encapsulation: private/protected attributes, get methods, and set methods. (6) There should be appropriate overloading and overriding methods. (7) OrderSystem should take advantage of the inheritance properties (e.g., use Snack variable regardless which snack instance as appropriate). (8) The prices for S, M, L, citrus fruit, nut snack can be hard coded in the program.
