设有如下代码:class Base{}public class MyCast extends Base{static boolean b1=false;static int i = -1;static double d = 10.1;public static void main(String argv[]){MyCast m = new MyCast();Base b = new Base();//Here}}则在 //Here处插入哪个代码将不出现编译和运行错误。A.b=m;B.m=b;C.d =i;D.b1 =i;
设有如下代码:
class Base{}
public class MyCast extends Base{
static boolean b1=false;
static int i = -1;
static double d = 10.1;
public static void main(String argv[]){
MyCast m = new MyCast();
Base b = new Base();
//Here
}
}
则在 //Here处插入哪个代码将不出现编译和运行错误。
A.b=m;
B.m=b;
C.d =i;
D.b1 =i;
