答案是c public static void fun() { } 这个是实例方法,所以只能用实例变量。好像应该是这样的。
同意!静态方法只能访问静态变量和其它的静态方法. since static methods don’t need any objects to be created before they are used, they cannot directly access non-static members or methods by simply calling those other members without referring to a named object (since non-static members and methods must be tied to a particular object).
public static void fun() {
}
