        g.drawString(str, 200, 200);
    }
}

这是终端的输出

我该怎么办？？我似乎无法弄清楚我的代码或我安装的 jdk 有什么问题。请帮我解决这个问题。我什至尝试通过从 .java 文件中删除小程序代码并创建一个 html 文件来单独使用 html，如下所示。我所有的浏览器都无法加载插件。是浏览器的问题还是小程序的问题？html代码：

<html>    
<head>
<title>ABCD</title>
<applet code  = App width=200 height=200>
</applet>
</html>

您的整个代码似乎都很好。这里的问题在于标签。将 .java 文件的名称放在双引号中，即使用如下

       code = "App" width=400,height =400
