What happens when you write your own constructor in Java and what must you pay attention to?
What will be an ideal response?
When you write your own constructor, you replace the automatically supplied version. Depending on your needs, a constructor you create for a class might be a default constructor or might require arguments. When you use a class as a superclass and the class has only constructors that require arguments, you must be certain that any subclasses provide the superclass constructor with the arguments it needs.
