Answer 1

Every class in Java is a subclass of the Object class. You need not extend the Object class because all the class by default inherit that class.

The Object class has a no argument default constructor which is called whenever you create an instance of a class in Java.

Answer 2

All classes have at least one constructor. If a class does not explicitly declare any, the Java compiler automatically provides a no-argument constructor, called the default constructor. This default is the Object class constructor if the class has no other parent.

public class Program
{
super(); // This is the call to the parent class constructor
}

Answer 3

An Object class constructor.. Since it's a super class for all classes...
