(The Stock class) 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.
