放置正确的光盘使用绘图面板连接四个Java游戏

标签： java swing graphics console java.util.scanner

我正在尝试使用用户输入和绘图面板在Java中创建Connect Four Game。两个人关掉了他们希望他们的作品进入的栏目。我在制作它时遇到了麻烦，因此下一回合已经放置的光盘留在了电路板上（因为每次都会弹出一个新的绘图面板和更新的电路板） （我们尝试使用GUI但失败了）。我也无法关闭转弯并每次都进行换色。非常感谢，这是我到目前为止所做的。

  • 不要将基于控制台的输入与GUI输出混合，这是两种不同的用户范例，需要不同的工作流程和管理方法
  • 不要使用import java.awt.BorderLayout; import java.awt.Color; import java.awt.Dimension; import java.awt.EventQueue; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.Point; import java.awt.RenderingHints;

以下是如何使用API​​而不是使用API​​的一个非常基本的示例。

ConnectFour 

    $mime = new Mail_mime();
    $mime->setFrom("ABCD");  //This doesn't work....
    $mime->setSubject('Testing');
    $mime->setTXTBody('This is a demo mail');
    $mime->addTo('a@a.com');
    $message_body = $mime->getMessage();
    $encodeMessage = base64url_encode($message_body);
    $message = new Google_Service_Gmail_Message();
    $message->setRaw($encodeMessage);
    $send = $service->users_messages->send('me', $message);
