Question

PUT IN JAVA PROGRAMMING

The StockB class:

Design a class named StockB that contains the following properties:
• Name of company
• Number of shares owned
• Value of each share
• Total value of all shares
and the following operations:
• Acquire stock in a company
• Buy more shares of the same stock
• Sell stock
• Update the per-share value of a stock
• Display information about the holdings
• The StockB class should have the proper constructor(s).
• Create/write a client class (program) to test and use your StockB class. In the client program,

you need to create objects of the StockB type and use those objects

to perform some meaningful and valid stock transactions.
