Answers:

Question 1: The Clothing version

-> As the Shirt inherits Clothing so the object of the Shirt class can call the method of Clothing.

Program:

class Clothing
{
void fold()
{
System.out.println("Clothing class Method!!");
}
}
class Shirt extends Clothing
{
}

class Test
{
public static void main(String args[])
{
Shirt myShirt=new Shirt();
myShirt.fold();
}
}

Output:

Question 2: The code compiles and runs.

class Clothing
{
void fold()
{

}
}
class Shirt extends Clothing
{

{
public static void main(String args[])
{
Clothing myShirt=new Shirt();
myShirt.fold();
}
}

Output:
