Update Bomb

Tommy, try using a structure like this to test?
public class BombMain {

	public static void main(String[] args) {
		Bomb b = new Bomb(6,1,1,1);
		
		while(!b.isExploded()){
			b.updateBomb();
		}
		System.out.println("Start boom");
		while(!b.isDoneExploding()){
			b.updateExplosion();
		}
		System.out.println("End boom");

	}

}
