运行时可调用浏览器打开一个网页 ， 网页地址在代码中的java代码怎么写？网页地址在代码中页面java代码的java代码写法如下页面java代码：
packagecom.test;
importjava.lang.reflect.Method;
//实现打开浏览器并跳到指定网址的类
publicclassBareBonesBrowserLaunch{
publicstaticvoidopenURL(Stringurl){
try{
browse(url);
}catch(Exceptione){
}
}
privatestaticvoidbrowse(Stringurl)throwsException{
//获取操作系统的名字
StringosName=System.getProperty("os.name","");
if(osName.startsWith("MacOS")){
//苹果的打开方式
ClassfileMgr=Class.forName("com.apple.eio.FileManager");
MethodopenURL=fileMgr.getDeclaredMethod("openURL",newClass[]{String.class});
openURL.invoke(null,newObject[]{url});
}elseif(osName.startsWith("Windows")){
//windows的打开方式 。
Runtime.getRuntime().exec("rundll32url.dll,FileProtocolHandler" url);
}else{
//UnixorLinux的打开方式
String[]browsers={"firefox","opera","konqueror","epiphany","mozilla","netscape"};
Stringbrowser=null;
for(intcount=0;countbrowsers.lengthbrowser==null;count)
//执行代码页面java代码，在brower有值后跳出页面java代码，
//这里是如果进程创建成功了，==0是表示正常结束 。
if(Runtime.getRuntime().exec(newString[]{"which",browsers[count]}).waitFor()==0)
browser=browsers[count];
if(browser==null)
thrownewException("Couldnotfindwebbrowser");
else
//这个值在上面已经成功的得到了一个进程 。
Runtime.getRuntime().exec(newString[]{browser,url});
}
}
}
//主方法测试类
publicstaticvoidmain(String[]args){
Stringurl="";
BareBonesBrowserLaunch.openURL(url);
}

如何在HTML页面中写java代码Java要运行html代码，需要运行在服务器端，也就是servlet容器中，经过容器编译解析，返回html静态内容，示例如下：
在servlet里面写就可以了
引入一系列包
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.*;
public class Servlet1 extends HttpServlet {
public void doGet(ServletRequest req,ServletResponse res)throws ServletException, IOException{try{PrintWriter pw=res.getWriter();//在浏览器输出需要
pw.println("scriptscript");}catch(exception e){="" e.printstacktrace();="" 为发现调试错误}}}=""
