Introduction

When you create an instance of a subclass, Java automatically calls the default constructor of the base class before it executes the subclass constructor.

For example, consider the following classes: 

class Ball
{
     public Ball()
      {
           System.out.println(
                 "Hello from the Ball constructor");
      }
}

class BaseBall extends Ball
{
     public BaseBall()
      {
           System.out.println(
                 "Hello from the BaseBall constructor");
      }
}
