浏览器不显示Java小程序 [英] browser doesn't show java applet
问题描述
我刚开始用Java小程序，发现这个网站，给出了一个教程。我输入了所有code，但小程序没有在我的浏览器中显示：HelloWorld.java
I'm just starting with java applets and found this website that gives a tutorial. I entered all the code but the applet didn't show up in my browser: HelloWorld.java
import java.applet.*;
import java.awt.*;
public class HelloWorld extends Applet
{
public void paint (Graphics g)
{
g.drawString("Hello World!", 300, 300);
}
}
这是我的HTML文件
And this is my HTML file
<HTML>
<HEAD>
<TITLE>Hello World Applet</TITLE>
</HEAD>
<BODY>
<H1>Hello World Applet</H1>
<applet code="HelloWorld.class" WIDTH=300 HEIGHT=300></applet>
</BODY>
</HTML>
我已经编译java文件（HelloWorld.class文件），并保存在我的桌面上的所有文件。我使用的Mac OSX山狮的最新版本的Safari。我试图在谷歌Chrome和它说要安装一个插件，我做，但没有更多的事？
I have compiled the java file (HelloWorld.class) and saved all the files on my desktop. I'm using the latest version of safari on mac osx mountain lion. I tried it in google chrome and it said to install a plugin and i did but nothing more happened?

让你知道你的小应用程序在浏览器中运行，如果你发现你所提到的尺寸的白色矩形，但如预期，因为一些问题，浏览器/ JRE小程序没有运行。
SO that you know your applet is running on the browser if you find a white rectangle of the dimensions you mentioned but the applet is not running as expected because of some problem with the browser/jre.
2日 - 我们使用的浏览器一般都是32位浏览器。做检查，如果你有安装Java的情况下在32位版本的浏览器是32位的。
2nd- Browsers that we use are generally 32 bit browsers. Do check if you have the 32 bit version of java installed in case your browser is a 32 bit-one.
3 - 要检查你的applet是否实际创建，请尝试使用appletviewer中使用的终端上运行的HTML文件
3rd- To check whether your applet is actually created, try running the html file using appletviewer using the terminal.
运行下面的无论是在任何您使用CMD /终端：
run the following either in cmd/terminal whichever you use:

或者如果你使用eclipse / netbeans的，他们通常有一个appletviewer中与IDE集成一起，使他们直接运行的appletviewer。
or if you are using eclipse/netbeans, they usually have a appletViewer integrated along with the IDE so they run the appletviewer directly.
