15. The equals( ) method override

• To override the equals() method of the Object class, add your own equals() method to the class.

• For example, the Product class could implement the method as follows:

  
      @Override
      public boolean equals( Object object )
      {
          if ( object instanceof Product )
          {
              Product product2 = (Product) object;
              if (
                  code.equals( product2.getCode() )
                  &&
                  description.equals( product2.getDescription() )
                  &&
                  price == product2.getPrice()
              )
              {
                  return true;
              }
          }
          return false;
      }//equals
