my own little program

[munchy1988]

well, i got bored in class, and made my own little "destry the world program", u kno, the usual.

heres to code for it. im just a beginner so its not that advanced.

class countries
{
	
	public static void main(String[] args)
	{		
		int seconds = 0;
		int countries = 0;
		int count = 0;
		String msg = "";
		String msg1= "";
		seconds = IO.getInt("How many seconds will the process take?");
		
		while ((seconds<1) || (seconds>50))
		{
			seconds = IO.getInt("Process is either too long or undefinable.  Please re-enter process time");
		}
		
                countries = IO.getInt("How many countries?");
		
		if (countries == 1)
		{
			msg1+= ("1 Billion Chinese People ");
		}
		
		if (countries == 2)
		{
			msg1+= ("China and Germany ");
		}
		
		if (countries == 3)
		{
			msg1+= ("China, Germany, and The Pinko Commies ");
		}
		
		if (countries == 4)
		{
			msg1+= ("China, Germany, Russia, and Japan ");
		}
		
		if (countries == 5)
		{
			msg1+= ("China, Germany, Russia, Japan, and another third world country with terrorists ");
		}
		
		if (countries == 6)
		{
			msg1+= ("China, Germany, Russia, Japan, France, and Mongolia ");
		}
		
		if (countries > 6)
		{
			msg1+= (countries + " countries ");
		}
		
		for (count = seconds; count > 0; count--)
		{
			msg +=(msg1 +"will be demolished in: " + count + '\n');
			IO.showMsg(msg);
			msg = new String("");
		}
		
		IO.showMsg(msg1 + "are now destroyed" + '\n' + '\n' +
					"The U.S. government has officially pwn3d you." + '\n' + '\n' +
					"**** Cheney now owns all of your assets.  Thank you for your participation in this program.");
		
		System.exit(0);
	}
}

well, what i want to kno is, instead of making a new IO.showMsg box appear, how can i make it count down to 0 with only the 1 box shoing up? is it even possible to do a thing like this with a time second delay?

**i probably should have mentioned this is in java...srry about that guys.
