Lab05 Hints and Tips

Part 1

• In Step 3, the inner class should look like:

private static class StockTickerThread extends Thread
{
	private String symbol;
	
	public StockTickerThread(String symbol)
	{
		this.symbol = symbol;
	}

	public void run()
	{
	}
}
		

• In Step 4b, use code like:

Random rand = new Random();

int sleep = r.nextInt(5000);

try
{
    TimeUnit.MILLISECONDS.sleep(sleep);
}
catch (InterruptedException e)
{
  System.out.println("Thread interrupted");
}
	    

• In Step 5a, use code like:

StockTickerThread t1 = new StockTickerThread("IBM");
StockTickerThread t2 = new StockTickerThread("Microsoft");	    
	    

• In Step 7c, your loop might look like:

while (cancel == false)
{
    . . .
}	    
	  

Part 2

• In Step 1, you can use the Eclipse New Class wizard to choose the superclass and add the java.lang.Runnable interface.
• In Step 2, to override methods in Eclipse, you can use the Source - Override/Implement Methods menu. The start and stop methods are from the Applet class.
• In Step 4b, your code might look like:

  me = new Thread(this);
  me.start();
