السلام عليكم ورحمة الله وبركاته

عندنا project مشروع في الجافا وحاولت احله لكن مو مفهوم شي يعني مادري كم class عندي, الي اعرفه ان output تكون في الكلاس الرئيسية لكن المشكلة في ال method ومثل كذا جدا اعاني صعوبة فيه


وهذا السؤال اخوي مستر احمد:

Write a java class named as Product.java representing a product you purchase from a supermarket. This class should have the following information about the Product:
· Product Name (String). (e.g. Milk , Chocolate, Tea e.t.c.)
· Company Name (String) (Al-marai, Galaxy , Lipton e.t.c)
· Make Date (Date). (Date of Make of Almarai Milk printed on the Bottle )
· Product Count( int) ( No of Products in the supermarket e.g. 5 )
Customer can visit and purchase the products from the supermarket. When the customer purchase a product its date of expiry must be displayed which is 1 week from the Make Date. Let’s assume that The Super Market has 5 different Products.

The Products class should have eight methods

· setProductName (String name) for setting the name of the Product.
· getProductName ( ) for returning the name of the Product.
· setCompanyName(String name) for setting the name of the Company of a Product.
· getCompanyName ( ) for returning the name of the Company of a Product.
· check ( ) for checking the availability of a Product in the super Market.
· setMakeDate (Date) for setting the Make date of a Product.
· getMakeDate (Date) for returning the Make date of a Product.
· toString() for printing a report that contains all of Products purchased from the super market.


Write a Java application (Main class) called ProductTest.java that lets the user to create six Objects of Product Class and then prints a report that contains all the five products purchased by a customer.
