Analyze the following code:

public class Test extends A {
public static void main(String[] args) {

Test t = new Test();

t.print();

}
}

class A {
String s;

A(String s) {

this.s = s;

}

public void print() {

System.out.println(s);

}
}

◦ The program does not compile because Test does not have a default constructor Test().
◦ The program compiles, but it has a runtime error due to the conflict on the method name print.
◦ The program would compile if a default constructor A(){ } is added to class A explicitly.
◦ The program has an implicit default constructor Test(), but it cannot be compiled, because its super class does not have a default constructor. The program would compile if the constructor in the class A were removed.
