Solution
The program has a compile error because class A does not have a default constructor. The program would compile and run if you change A a = new A() to A a = new A("5").

Analyze the following code and choose two correct statements from below. 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); } } Group of answer choicesThe program does not compile because Test does not have a default constructor Test().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.The program would compile if a default constructor A(){ } is added to class A explicitly.The program compiles, but it has a runtime error due to the conflict on the method name print.
