/*********************************************************************************
- (The Stock class) Following the example of the Circle class in Section 9.2, *
- design a class named Stock that contains: *
-
* - ■ A string data field named symbol for the stock’s symbol. *
- ■ A string data field named name for the stock’s name. *
- ■ A double data field named previousClosingPrice that stores the stock *
- price for the previous day. *
- ■ A double data field named currentPrice that stores the stock price for the *
- current time. *
- ■ A constructor that creates a stock with the specified symbol and name. *
- ■ 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 ORCL, the name *
- Oracle Corporation, and the previous closing price of 34.5. Set a new current *
- price to 34.35 and display the price-change percentage. *
