• A better programming style might be to name the constructor parameters exactly as the class data members:

  
  public Product(String code, String description, double price)
  {
      this.code = code;
      this.description = description;
      this.price = price;
  }
  
  

  To disambiguate between local constructor parameters and object's member variabled the this keyword is applied in front of the data field names.
