1. An electronics company needs to implement a simple stock control system. You are required to write a Java application which contains a class called StockItem together with a main method class called StockDemo. Information for each type of stock item consists of:

inventory identifier (e.g. A654Y);

quantity in stock (e.g. 350);

demand rate (quantity removed from stock each working day, assumed constant, e.g. 50);

re-order quantity (the size of an ordered batch of items, assumed constant, e.g 1000);

lead-time (number of working days delay between placing and receiving an order for a batch, e.g. 5).

The class StockItem should include fields for each of the above data items and should also include each of the following:

a default constructor that sets all fields to null or zero as appropriate;

a constructor with arguments for all fields;

set methods for all fields;

accessor methods for each of the fields;

a method to update the stock quantity when a batch is received;

a method called isReOrderPoint( ) that returns true if a batch needs to be re-ordered for this stock item and false otherwise;

a toString method that returns a description of this StockItem.

Add Java statements to your main method to thoroughly test your class. question #Minimum 100 words accepted#
