1. Goal

A hair salon prices appointments. The checkout program calls one class for each appointment. The class returns the price of the appointment in euro.

2. Open questions

None.

3. Context

• Interface {{P}}IF_SALON_PRICE exists in package $TMP. It is active.
• The interface has the type TY_SERVICE (CHAR 10) and the type TY_AMOUNT (P length 8, 2 decimals).
• The interface has the constant structure C_SERVICE with the components CUT, COLOUR and PERM.
• The interface has one method: PRICE IMPORTING iv_service TYPE ty_service iv_child TYPE abap_bool RETURNING VALUE(rv_price) TYPE ty_amount.
• iv_child is abap_true when the customer is under 12 years.

4. Contract

• Create the class {{P}}SALON_PRICER in package $TMP.
• The class is public, final, and has a public constructor without parameters.
• The class implements {{P}}IF_SALON_PRICE.

5. Business rules

1. The price is in euro with two decimals.
