STOCK PROGRAM:

public class Stock { private String Symbol; private String name; private double previousClosingPrice; private double currentPrice; Stock(String symbol, String name) { this.Symbol = symbol; this.name = name; }

public String getSymbol() { return Symbol; }

public void setSymbol(String symbol) { Symbol = symbol; }

public String getName() { return name; }

public void setName(String name) { this.name = name; } public double getChangePercent() { return ((currentPrice - previousClosingPrice) * 100) / currentPrice; }

public void setPreviousPrice(double previous) { previousClosingPrice = previous; }

public void setCurrentPrice(double current) { currentPrice = current; }

}

STOCK TEST PROGRAM:

import java.util.Scanner;

public class StockTest { public static void main(String [] argv){ Scanner input = new Scanner(System.in); System.out.println("Please input the stock symbol: "); String symbol = input.nextLine(); System.out.println("Please input the stock name: "); String name = input.nextLine(); Stock stock = new Stock(symbol, name); // set the previous price System.out.println("Please set the previous price: "); stock.setPreviousPrice(input.nextDouble()); // set the current price System.out.println("Please set the current price: "); stock.setCurrentPrice(input.nextDouble()); System.out.println("Price Change percetage of stock is :" + stock.getChangePercent() +"% "); } }

Following the instructions in the problem statement, design and implement a Java program for programming exercise 9.2, page 360 (name it Stock.java).

Next, develop a test program in a separate file (call it TestStock.java) to create object ORCL as stated in the problem statement. Now, modify the test program to create 2 more stock objects (say MS and Google) and test all class methods on these 2 objects in logical order and display meaningful information after each method call. Document your code, and organize and space the outputs properly. Use escape characters and formatting objects when applicable.
