FUNCTIONAL DESCRIPTION

            This is a MIDlet application meant to be run on small mobile devices. In this application user can store items in a list and refer this list while shopping, deleting and adding items, as the case may be. The list is stored using MIDP Record Management System or RMS.

            The first file ShoppingItem.java simply describes the structure of item that has to be stored. The second one, ShoppingDB.java is the main file where all the functions used for interacting with RMS are defined. The final file, ShoppingList.java describes the interface with the user i.e. the lcdui components and calls functions defined in ShoppingDB.java.

            The functionality of this MIDlet is to add and delete elements from the list and persistently store the list i.e. even after closing this MIDlet; the list can be populated again by again launching this MIDlet.

            The structure of item is defined simply as

public String SItem;
