In programming, objects have properties, which describe the object’s characteristics.
True
False
Portfolio
Instructions:
You are working for a financial advisor who creates portfolios of financial securities for his clients. A portfolio is a conglomeration of various financial assets, such as stocks and bonds, that together create a balanced collection of investments.
When the financial advisor makes a purchase of securities on behalf of a client, a single transaction can include multiple shares of stock or multiple bonds.
It is your job to create an object-oriented application that will allow the financial advisor to maintain the portfolios for his/her clients. You will need to create several classes to maintain this information: Security, Stock, Bond, Portfolio, and Date.
The characteristics of stocks and bonds in a portfolio are shown below:
Stocks: Bonds:
Purchase date (Date) Purchase date (Date)
Purchase price (double)…
