Question

我使用添加到html的Applet。但这张照片并没有表演。没有错误消息。什么地方出了错？我用appletviewer来测试。就像没有的那样。

HTMLCODE

<body>
<applet code=SS.class 
        archive="av.jar, httpclient-4.2.2.jar, httpcore-4.2.2.jar, commons-logging-1.1.1.jar, fluent-hc-4.2.2 httpclient-cache-4.2.2, httpmime-4.2.2"
   width=719 height=679>
</applet>
</body>
</html>

我的代码很混乱所以我只是打开他的框架我类似的框架不应该正常运行

    }

    @Override

    } 



   }

Answer 1

我认为在public class SS extends Applet中创建main而不是必须创建init()方法。

public class SS extends Applet
 { 
   /**
    * 
    */
   public void init() {
     win1 bb = new win1(); 
     getContentPane().add(bb )
   }
}

但首先，您必须了解applet How to Make Applets

的基础知识

Applet无法启动
