PLEASE I NEED HELP COMPILING THIS JAVA CODE. THIS IS FOR A STOCK MARKET TRADING PROGRAM. PLEASE HELP:

// MYOSM.java // Make Your Own Stock Market: A simple stock market simulator that contains a // few stocks and their current prices (and deltas). It randomly adjusts the // prices on stocks to give a dynamic feel to the data. // import javax.swing.*; import java.awt.*; import java.util.*;

Stock[] market = { new Stock("JTree", 14.57), new Stock("JTable", 17.44), new Stock("JList", 16.44), new Stock("JButton", 7.21), new Stock("JComponent", 27.40) }; boolean monitor; Random rg = new Random(); Thread runner;

public MYOSM() { // Not meant to be shown as a real frame super("Thread only version . . ."); runner = new Thread(this); runner.start(); }

// This version creates a real frame so that you can see how the typical // stocks get updated.

getContentPane().add(new JLabel("Trading is active. " + "Close this window to close the market."), BorderLayout.CENTER); runner = new Thread(this); runner.start(); }

// Here's the heart of our stock market. In an infinite loop, just pick a // random stock and update its price. To make the program interesting, we'll // update a price every second. public void run() { while(true) { int whichStock = Math.abs(rg.nextInt()) % market.length; double delta = rg.nextDouble() - 0.4; market[whichStock].update(delta); if (monitor) { market[whichStock].print(); } try { Thread.sleep(1000); } catch(InterruptedException ie) { } } }

public Stock getQuote(int index) { return market[index]; }

// This method returns the list of all the symbols in the market table public String[] getSymbols() { String[] symbols = new String[market.length]; for (int i = 0; i < market.length; i++) { symbols[i] = market[i].symbol; } return symbols; }

public static void main(String args[]) { MYOSM myMarket = new MYOSM(args.length > 0); myMarket.setVisible(true); } }
