StockHoldingMain.java

public class StockHoldingMainCode {

   public static void main(String[] args) {

       StockHolding holdings = new StockHolding("AAPL", 19,103.97);
       holdings.setCurrentSharePrice(105.5);
       System.out.println("APPLE INITIAL COST: " + holdings.getInitialCost());
       System.out.println("APPLE PROFIT: " + holdings.getCurrentProfit());
       System.out.println(holdings);
   }
}

PortfolioDriver.java

public class PortfolioDriverVal {

   public static void main(String[] args) {
       PortfolioList pp1 = new PortfolioList();
       PortfolioList pp2 = new PortfolioList();
       pp1.add(new StockHolding("AAPL",3, 100 ));
       pp1.add(new StockHolding("AAPP",2, 200 ));
      
       pp2.add(new StockHolding("ABCD",3, 500 ));
       pp2.add(new StockHolding("EFGH",6, 600 ));
       pp2.add(new StockHolding("IJKL",7, 700 ));
       pp2.add(new StockHolding("MNOP",8, 800 ));
       System.out.println(pp1.toString());
       System.out.println("--------------------------------");
       System.out.println(pp2.toString());

       StockHolding s1 = pp1.find("AAPP");
       System.out.println(s1.toString());
       StockHolding s11 = pp2.find("IJKL");
       System.out.println(s11.toString());
       System.out.println("-------REMOVED SECOND PORTFOLIO ALL OBJECTS---------------");
       pp2.remove("ABCD");
       pp2.remove("EFGH");
       pp2.remove("IJKL");
       pp2.remove("MNOP");
       System.out.println(pp2.toString());
