You have been hired to create a Grilled Rump Steak ordering app. The app should have a class named GrilledRumpSteak which contains data about a single rump. The GrilledRumpSteak class should include the following:

▪ Private instance variables to store the size of the rump (either small, medium, or large), the number of salsa toppings, the number of tomato toppings, and the number of mushroom toppings.
▪ Constructor(s) that set all the instance variables.
▪ Public methods to get and set the instance variables.
▪ A public method named calcCost( ) that returns the cost of the rump as a double. The Grilled
Rump Steak cost is determined by: Large: R200 + 30 per topping Medium: R150 + R20 per
topping Small: R120 + R15 per topping
▪ public method named getDescription( ) that returns a String containing the rump size, quantity
of each topping.
Write test code to create several grilled rump steaks and output their descriptions. For example, a large rump with one salsa, one tomato, and two mushroom toppings should cost a total of R320. Now Create a GrilledRumpSteakOrder class that allows up to three grilled rump steaks to be saved in order. Each grilled rump steak saved should be a GrilledRumpSteak object. Create a method calcTotal() that returns the cost of the order

Answer:

Here is the Java code for the Grilled Rump Steak ordering app:

```

public class GrilledRumpSteak {

private String size;

private int salsaToppings;

private int tomatoToppings;

private int mushroomToppings;

public GrilledRumpSteak(String size, int salsaToppings, int tomatoToppings, int mushroomToppings) {

this.size = size;

this.salsaToppings = salsaToppings;

this.tomatoToppings = tomatoToppings;

this.mushroomToppings = mushroomToppings;

}

public String getSize() {

return size;

}

public void setSize(String size) {

this.size = size;

}

public int getSalsaToppings() {

return salsaToppings;

}

public void setSalsaToppings(int salsaToppings) {

this.salsaToppings = salsaToppings;

}

public int getTomatoToppings() {

return tomatoToppings;

}

public void setTomatoToppings(int tomatoToppings) {

this.tomatoToppings = tomatoToppings;

}

public int getMushroomToppings() {

return mushroomToppings;

}

public void setMushroomToppings(int mushroomToppings) {

this.mushroomToppings = mushroomToppings;

}

public double calcCost() {

double cost = 0;

if (size.equals("Large")) {

cost = 200 + (30 * (salsaToppings + tomatoToppings + mushroomToppings));

} else if (size.equals("Medium")) {

cost = 150 + (20 * (salsaToppings + tomatoToppings + mushroomToppings));

} else if (size.equals("Small")) {

cost = 120 + (15 * (salsaToppings + tomatoToppings + mushroomToppings));

}

return cost;

}

public String getDescription() {

return size + " rump with " + salsaToppings + " salsa topping(s), " + tomatoToppings + " tomato topping(s), and " + mushroomToppings + " mushroom topping(s)";

}

}

```

Here is the Java code for the GrilledRumpSteakOrder class that allows up to three grilled rump steaks to be saved in order:

```

public class GrilledRumpSteakOrder {

private ArrayList<GrilledRumpSteak> order;

public GrilledRumpSteakOrder() {

order = new ArrayList<GrilledRumpSteak>();

}

public void addGrilledRumpSteak(GrilledRumpSteak rump) {

if (order.size() < 3) {

order.add(rump);

} else {

System.out.println("Maximum of 3 Grilled Rump Steaks per order.");

}

}

public double calcTotal() {

double total = 0;

for (GrilledRumpSteak rump : order) {

total += rump.calcCost();

}

return total;

}

}

```

To test the code, you can write the following code in the main method:

```

public static void main(String[] args) {

GrilledRumpSteak rump1 = new GrilledRumpSteak("Large", 1, 1, 2);

GrilledRumpSteak rump2 = new GrilledRumpSteak("Medium", 2, 0, 1);

GrilledRumpSteak rump3 = new GrilledRumpSteak("Small", 0, 3, 1);

System.out.println(rump1.getDescription() + " - Cost: R" + rump1.calcCost());

System.out.println(rump2.getDescription() + " - Cost: R" + rump2.calcCost());

System.out.println(rump3.getDescription() + " - Cost: R" + rump3.calcCost());

GrilledRumpSteakOrder order = new GrilledRumpSteakOrder();

order.addGrilledRumpSteak(rump1);

order.addGrilledRumpSteak(rump2);

order.addGrilledRumpSteak(rump3);

System.out.println("Total cost of order: R" +
