A data field named symbol (e.g. $, ORCL) for the stocks symbol.

A data field named name (e.g. dollar, Oracle Corporation) for the stocks name.

A data field named previousClosingPrice that stores the stock price for the previous day.

A 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.

A default constructor that creates a default stock.
