import View.MainView;
import java.awt.Color;
import java.awt.Graphics2D;

public class Start {protected static MainView mainView;
public static void main(String args[]) {
mainView = new MainView();
mainView.setVisible(true);//Graphics2D graphics2D = mainView.getGraphics2D(); //graphics2D.setPaint(Color.BLACK); mainView.paintScreen();}
}
[/code]
package View;
import java.awt.Color;
