Write a program that uses nested loops to display the following lines
``` 1 2 4 6 2 2 4 6 3 2 4 6 4 2 4 6 ```
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); } }``` a. The program does not compile because Test does not have a default constructor Test(). b. 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. c. The program would compile if a default constructor A(){ } is added to class A explicitly. d. The program compiles, but it has a runtime error due to the conflict on the method name print.
