1. 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 previous 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. Write a test program that creates a Stock object with the 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.
