Inherit _Object class usage _toString and equals methods _ override toString

• The Object class is the base class of all Java classes.
• If the class declaration does not use the extends keyword to indicate its base class, the default base class is the Object class.

public class Person{      public class Person extends Object{
    ............           ................
}                          }

• Rewrite: toString method:
  1. Default return: package name + class name + @ + hash code
  2. Can be rewritten!
