所以在静态方法中调用非静态方法时,编译器会报错(Cannot make a static reference to the non-static method func() from the type A)。 java中不能将方法体内的局部变量声明为static main()函数是静态的,没有返回值,形参为数组。 非静态成员的可以随便调用静态成员 原来静态这么反人类,那要this的干什么呢? 大...

楼上回答的不知所以!AddStudentDAO是接口,不能被实例化,变量引用也不对!下面是我给你改的。劝楼主一句话,忠言逆耳:还是先学好j2se基础再学框架吧。Override public ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response)throws Exception...
代码如上,在System.out.println那行有错误,错误信息如下: Cannot make a static reference to the non-static method sum(int, int) from the type Test,里面提示只要把sum方法改成static即可,究竟是怎样一回事呢?先谢园友了。java bobo2018 | 初学一级 | 园豆:135 提问于:2014-12-28 13:49 <...
