Question

Java

Create an abstract Product Class

Add the following private attributes:

• name

• sku (int)

• price (double)

Create getter/setter methods for all attributes

Create a constructor that takes in all attributes and sets them

Remove the default constructor
Override the toString() method and return a String that represents the building object that is formatted

nicely and contains all information (attributes)

Create a FoodProduct Class that extends Product

Add the following private attributes:

• expDate (java.util.Date) for expiration date

• refrigerationTemp (int) if 70 or above, none necessary, otherwise it will be a lower number

• servingSize (int) in grams

• caloriesPerServing (int)

• allergens (ArrayList<String>)

  Create getter/setter methods for all attributes

  Create a constructor that takes in all attributes for product and food product. Call the super constructor and then set the expDate, refrigerationTemp, servingSize, caloriesPerServing and allergens.

• Remove the default constructor

  Override the toString() method and return a String that represents the food product object that is formatted nicely and contains all information (super toString and the private attributes)

Create a CleaningProduct Class that extends Product

Add the following private attributes:

• String chemicalName

• String hazards

• String precautions

• String firstAid

• ArrayList<String> uses (e.g. kitchen, bath, laundry, etc)

Create getter/setter methods for all attributes

Create a constructor that takes in all attributes for product and food product. Call the super constructor and then set the chemical name, hazard, precautions, firstAid and uses. TIP: try generating the constructor, it will add the super stuff for you. (Also, see Lynda inheritance videos.)

Remove the default constructor

Override the toString() method and return a String that represents the cleaning product object that is formatted nicely and contains all information (super toString() and the private attributes)

Create the interface Edible which contains the following method signatures:

• public Date getExpDate();

• public void setRefrigerationTemp(Int refrigerationTemp)

• public int getRefrigerationTemp();

• public void setExpDate(Date expDate) ;

• public int getServingSize() ;

• public void setServingSize(int servingSize) ;

• public int getCaloriesPerServing() ;

• public void setCaloriesPerServing(int caloriesPerServing);

• public String getAllergens() ;

• public void setAllergens(ArrayList<String> allergens) ;

Create the interface Chemical which contains the following method signatures

• public String getChemicalName();

• public void setChemicalName(String chemicalName) ;

• public String getHazards() ;

• public void setHazards(String hazards);

• public String getPrecautions() ;

• public void setPrecautions(String precautions) ;

• public ArrayList<String> getUses() ;

• public void setUses(ArrayList<String> uses) ;

• public String getFirstAid() ;

• public void setFirstAid(String firstAid) ;

Modify the FoodProduct Class to implement Edible, be sure to add the @Override before any methods that were there (get/set methods) that are also in the Edible interface.

Modify the CleaningProduct Class to implement Chemical, be sure to add the @Override before any methods that were there (get/set methods) that are also in the Chemical interface.

Create your main/test class to read products from a file, instantiate them, load them into an ArrayList and then print them nicely to the console at the end of your program. See instructor note about reading the file as the lengths of the lines may be different depending on the list of allergens. It is also comma delimited rather than by spaces. You will have to read an entire line, split its contents and then store the information into variables. The last element(s) are the allergens that you will have to store to an ArrayList.
