Java program,Define a class named FruitJuice with the following description: Instance variables/data members: int product_code- stores the product code number. String flavour- stores the flavour of the juice(eg:orange,apple) String pac_type- stores the type of packaging(eg:terapack) int pack_size- stores package size(eg:200ml,400ml) int product_price- stores the price of the product. Member methods: 1.FruitJuice()-Default constructor to initialize integer data members to 0 and string data members to "". 2.void input()-To input and store the product code,flavour,pack type,pack size and product price. 3.void discount()-To reduce the product price by 10. 4.void display()-To display the product code,flavour,pack type,pack size and prduct price.
