execute是啥意思
public class BookAddAction extends Action{
public ActionForward execute(ActionMapping mapping,ActionForm form,
HttpServletRequest request,HttpServletResponse response)
throws Exception {
BookService service = new BookServiceImpl();
service.addBook((BookAddForm)form,request);
return mapping.findForward("main");
}
}帮忙给解释下上面的含义

execute 是方法名
public class BookAddAction extends Action{ //类bookaction 从 action继承
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)//一个公共方法execute,返回类型为ActionForwar,包括了四个参数
throws Exception {//抛出异常
BookService service = new BookServiceImpl();//创建BOOKSERVICE 类型的对象引用
service.addBook((BookAddForm)form, request);//调用addbook方法,将其中的一个参数强制转换为bookaddform类型
return mapping.findForward("main");
}
}

这就句英文的意思：could not execute menu item? 你上次的这个问题你是怎么解决的`?please execute'setup.exe'for install or upg 英语翻译Execute active program with(START)；Machining;Main Progru 英语翻译While the execute-only memory (XOM) architecture,and the please execute'setup.exe'for install or upgrade. 英语翻译Kindly find the exclusivity contract and also execute th 英语翻译inwitness where of.i execute this certificate and affix please execute ' setup.exe ' for install or upgrade 英语翻译in witness whereof,i execute this certificate and affix please execute ' setup.exe ' for install or upgrade 英语翻译This enables us to develop and execute aggressive busine 英语翻译WHEREAS,the Parties mutually desire to execute this Cont
