package edu.hfcc;

/*
* Create Java application that will create Fruit class and Bread class
*
* Fruit class will have 3 data fields name and quantity which you can change.
* The third data field price should always be 2.0
* Bread class will have 3 data fields name, quantity and price. All three data fields can change.
*
* Create method that creates the string used write to console and return from execute()
*
* In GroceryApp
* Create method to calculate totalPrice for fruit
* Create method to calculate totalPrice for bread
* Create method to print to console use EXACLTY like example below
*
* Data to use
* Bread:     Name=French,    Quantity=2,   Price=3.0
* Fruit:   Name=Apple,    Quantity=5,   
*
* EXAMPLE TO Console
* French
        2 @ 3.0       6.0
Apple
      5 @ 2.0       10.0
---------------------

public class Grocery {

   private static final char NEW_LINE = '\n';
   private static final String TAB = "\t";
  
   public String execute(){
      
       Fruit fruitOne = new Fruit();
       fruitOne.setName("Apple");
       fruitOne.setQuantity( 5);
      
       String fruits = constructOutputFruit(apple);
       System.out.println(fruits);

       return fruits;
   }
   private String constructOutputFruit(Fruit fruit1) {
       String apple = fruit1.getName() + NEW_LINE + fruit1.getQuantity() + TAB + fruit1.getPrice();
      
       return apple + NEW_LINE;
   }
}

here are my classes:

Fruit:

package edu.hfcc;

public class Fruit {

   private String name;
   private int quantity;
   private float price;
  
   public Fruit(){
       this.price = (float)2.0;
       }
  

   public String getName() {
       return name;
   }

   public void setName(String name) {
       this.name = name;
   }

   public int getQuantity() {
       return quantity;
   }

   public void setQuantity(int quantity) {
       this.quantity = quantity;
   }

   public float getPrice() {
       return price;
   }
}

Bread:

package edu.hfcc;

public class Bread {

   private String name;
   private int quantity;
   private float price;
   public String getName() {
       return name;
   }
   public void setName(String name) {
       this.name = name;
   }
   public int getQuantity() {
       return quantity;
   }
   public void setQuantity(int quantity) {
       this.quantity = quantity;
   }
   public float getPrice() {
       return price;
   }
   public void setPrice(float price) {
       this.price = price;
   }
  

}

class Fruit {
private String name;
private int quantity;
private float price;
  
public Fruit(){
this.price = (float)2.0;
}
  
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getQuantity() {
return quantity;
}
public void setQuantity(int quantity) {
this.quantity = quantity;
}
public float getPrice() {
return price;
}
}

class Bread {
private String name;
private int quantity;
private float price;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getQuantity() {
return quantity;
}
public void setQuantity(int quantity) {
this.quantity = quantity;
}
public float getPrice() {
return price;
}
public void setPrice(float price) {
this.price = price;
}
  
}

  

class GroceryApp
{
   public static void main (String[] args)
   {
  
Bread bread1 = new Bread();
bread1.setName("French");
bread1.setQuantity(2);
bread1.setPrice(3.0f);
  
System.out.println(bread1.getName() + "\n" + bread1.getQuantity() + "@"+ bread1.getPrice() +"\t"+totalPriceBread(bread1));

Fruit fruit1 = new Fruit();
fruit1.setName("Apple");
fruit1.setQuantity( 5);

System.out.println(fruit1.getName() + "\n" + fruit1.getQuantity() + "@"+ fruit1.getPrice() +"\t"+totalPriceFruit(fruit1));

System.out.println("------------------------------");
System.out.println("\t"+(totalPriceFruit(fruit1)+totalPriceBread(bread1)));
   }

  

public static float totalPriceFruit(Fruit f)
{
    return f.getQuantity() * f.getPrice();
}
public static float totalPriceBread(Bread b)
{
    return b.getQuantity() * b.getPrice();
}
}

      
Output:

French
