Use the following JAVA sample code to answer the following question:

CODE:

public class Exercise09_02 { public static void main(String[] args) { Stock stock = new Stock("SUNW", "Sun MicroSystems Inc."); stock.setPreviousClosingPrice(100);

// Set current price stock.setCurrentPrice(90);

// Display stock info System.out.println("Previous Closing Price: " + stock.getPreviousClosingPrice()); System.out.println("Current Price: " + stock.getCurrentPrice()); System.out.println("Price Change: " + stock.getChangePercent() * 100 + "%"); } }

class Stock { }

QUESTION:

9.2 (The Stock class) Following the example of the Circle class from Section 9.2, design a class named Stock that contains:

* A string data field named symbol for the stocks symbol.

* A string data field named name for the stocks 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.
