Consider the following class definition:
1. public class Test extends Base {
2. public Test(int j) {
3. }
4. public Test(int j, int k) {
5. super(j, k);
6. }
7. }
Which of the forms of constructor must exist explicitly in the definition of the Base class?
an anyone solve my prob

Base() {}
Base(int j, int k) {}

could u eplain me how Base(){}??

Base() because in any child class constructor, if there's no explicit call to this(..) or supre(..), the compiler will implicitly insert super(). So, there has to be a Base() in the parent class.
I hope this helps.
