推荐答案
您有两种选择：结果
1.使用附带的JDK 的appletviewer 来只看到一个最基本的浏览器搜索的小程序工作
2.嵌入applet标记的HTML页面。
You have two options:
1. to use appletviewer which comes with your JDK to just see the applet work in a bare-bones browser
2. embed the applet tag in your HTML page.
<html>
<title>My Applet</title>
<body>
<applet code="PrintApplet.class" width="400" height="400"></applet>
</body>
</html>
但因为它的立场，＆LT;小程序方式＆gt; 已去precated结果
所以，这里是你做什么：结果
1.添加到您的＆LT; HEAD＆GT; ：＆LT;脚本SRC =http://java.com/js/deployJava.js ＆GT;＆LT; / SCRIPT＆GT; 结果
2.添加到您的＆LT;身体GT; ：
But as it stands, <applet> has been deprecated.
So, here is what you do:
1. Add this to your <head> : <script src="http://java.com/js/deployJava.js"></script>
2. Add this to your <body>:
<script>
var attributes = {codebase:'http://my.url/my/path/to/codebase',
code:'my.main.Applet.class',
archive: 'my-archive.jar',
width: '800',
height: '600'};
var parameters = {java_arguments: '-Xmx256m'}; // customize per your needs
var version = '1.5' ; // JDK version
deployJava.runApplet(attributes, parameters, version);
</script>
再次作为HTML5的，＆LT; HEAD＆GT; 则不需要，所以你可以只输入＆LT;脚本＆GT; ...＆LT; / SCRIPT＆GT;
Again, as of HTML5, <head> is not needed so you can just type <script>....</script>
这是取自的回答。
