Class Stock

(The Stock class) Design a class named Stock to represent a company’s stock that contains:
A private string data field named symbol for the stock’s symbol.
A private string data field named name for the stock’s name.
A private float data field named previousClosingPrice that stores the stock price for the previous day.
A private float data field named currentPrice that stores the stock price for the current time.
A constructor that creates a stock with the specified symbol, name, previous price, and current price.
A get method for returning the stock name.
A get method for returning the stock symbol.
Get and set methods for getting/setting the stock’s previous price.
Get and set methods for getting/setting the stock’s current price.
A method named getChangePercent() that returns the percentage changed from previousClosingPrice to currentPrice.
Draw the UML diagram for the class, and then implement the class. Write a test program that creates a Stock object
with the stock symbol INTC, the name Intel Corporation, the previous closing price of 20.5, and the new current
price of 20.35, and display the price-change percentage.
