有Java编写一个输出“Hello world!”的Applet 程序和嵌入该Applet的HYML页面

(1) 编辑Applet 的java源文件 创建文件夹C:\ghq，在该文件夹下建立 HelloWorld.java 文件的源代码如下： import java.awt.*; import java.applet.*; public class HelloWorld extends Applet //继承Applet类，这是Applet Java程序的特点 { public void paint(Graphics g ) { g.drawString("Hello World!",5,35)； } } 保存上述程序在C:\ghq\HelloWorld.java文件里。 (2)编译Applet 编译HelloWorld.java源文件可使用如下JDK命令： C:\ghq\javac HelloWorld.javaEnter 注意：如果编写的源程序违反了Java编程语言的语法规则，Java编译器将在屏幕上显示语法错误提示信息。源文件中必须不含任何语法错误，Java编译器才能成功地把源程序转换为appletviewer和浏览器能够执行的字节码程序。 成功地编译Java applet之后生成响应的字节码文件HelloWorld.class的文件。用资源管理器或DIR命令列出目录列表，将会发现目录C:\ghq中多了一个名为HelloWorld.class的文件。 (3)创建HTML文件 在运行创建的HelloWorld.class 之前，还需创建一个HTML文件，appletviewer或浏览器将通过该文件访问创建的Applet。为运行HelloWorld.class, 需要创建包含如下HTML语句的名为HelloWorld.html的文件。 HTML TITLEHelloWorld! Applet/TITLE APPLET CODE="HelloWorld.class" //这里应该是HelloWorld.class WIDTH=200 HEIGHT=100 /APPLET /HTML 本例中，APPLET语句指明该Applet字节码类文件名和以像素为单位的窗口的尺寸。虽然这里HTML文件使用的文件名为HelloWorld.HTML，它对应于HelloWorld.java的名字，但这种对应关系不是必须的，可以用其他的任何名字(比如说Ghq.HTML)命名该HTML文件。但是使文件名保持一种对应关系可给文件的管理带来方便。 (4)执行 HelloWorld.html 如果用appletviewer运行HelloWorld.html,需输入如下的命令行： C:\ghq\appletviewer HelloWorld.htmlENTER 可以看出，该命令启动了appletviewer并指明了HTML文件，该HTML文件中包含对应于HelloWorld 的APPLET语句。 如果用浏览器运行HelloWorld Applet，需在浏览器的地址栏中输入HTML文件URL地址。
