这有一道JAVA认证题,有谁会,帮帮忙!
有两个类,分别在两个文件中
public class Base{
public void method(int i){
System.out.println("Value is "+i);
}
}
public class Test extends Base{
public Test(int j){
}
public Test(int j,int k){super(j,k);}
}
问:Which of the following forms of constructor must exist explicitly in the definition of the Base class?
A. Base(){}
B. Base(int j){}
C.Base(int j,int k){}
D.Base(int j,int k,int L){}
谁知道答案,为什么,请指教
