在Eclipse中，我應該如何更改我的程序的入口點。 我有兩個獨立的包，每個都有靜態主要方法。在運行標題包中的主要方法之後，我現在將在主包中找到我原來的靜態主要方法。更改在eclipse中運行哪個main（）
我希望發生的是：
顯示標題畫面，並且如果用戶選擇玩遊戲然後調用Game.main（）
這裏有兩類：
package game.title;
import game.main.entities.movement.MenuKeyListener;
import game.main.graphics.ImageLoader;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.FileNotFoundException;
import java.io.IOException;
import javax.swing.*;
import src.game.main.Game;
// Referenced classes of package game.main:
// MenuKeyListener, Game
public class TitleScreen extends JFrame
{
class MyCanvas extends Canvas
{
public void paint(Graphics g)
{
super.paint(g);
g.drawImage(image, 0, 0, TitleScreen.SCREENHEIGHT, TitleScreen.SCREENWIDTH, this);
}
public void update(Graphics g)
{
if(TitleScreen.toggle == 0)
{
g.clearRect(0, 0, TitleScreen.SCREENWIDTH, TitleScreen.SCREENHEIGHT);
g.drawImage(image, 0, 0, TitleScreen.SCREENHEIGHT, TitleScreen.SCREENWIDTH, this);
int xCord[] = {
322, 350, 350
};
int yCord[] = {
533, 533, 553
};
g.setColor(Color.CYAN);
g.fillPolygon(xCord, yCord, 3);
} else
if(TitleScreen.toggle == 1)
{

g.drawImage(image, 0, 0, TitleScreen.SCREENHEIGHT, TitleScreen.SCREENWIDTH, this);

}
}

System.out.println("BYE!");
System.exit(0);
}

嘗試運行TitleScreen類我進去之後我的控制檯：
錯誤：無法找到或加載主類game.title.TitleScreen
