CafeDemo put it in a package named cafecom
public class CafeDemo {
public static void main(String[] args) {
CoffeeCup cupOne = new CoffeeCup(2.85, "Tall");
CoffeeCup cupTwo = new CoffeeCup(1.95, "Short");
Cafe Starbucks = new Cafe();
CoffeeCup [] cups = {cupOne, cupTwo};
System.out.println("Total Cost is: " +
Starbucks.getTotalCost(cups));
System.out.println(Starbucks.getMessage());
}
}
Cafe put it in a package named cafecom
Cafe
-totalCost: double
- message: String
+getTotalCost(Cup[]):double
+getMessage(): String
CoffeeCup put it in a package named coffeecupcom
CoffeeCup
-price: double
-size: String
+getPrice():double
+getSize():String
When you run the CafeDemo class, the following output will be produced:
Total Cost is: 4.80
Thank you for visiting Starbucks
You should implement all methods in classes Cafe and CoffeeCup, and add any necessary constructors.
You are not allowed to make any modifications to the CafeDemo class
Cafe
-totalCost: double
- message: String
+getTotalCost(Cup[]):double
+getMessage(): String
Explanation / Answer
CafeDemo.java
public class CafeDemo {
public static void main(String[] args) {
CoffeeCup cupOne = new CoffeeCup(2.85, "Tall");
CoffeeCup cupTwo = new CoffeeCup(1.95, "Short");
Cafe Starbucks = new Cafe();
CoffeeCup [] cups = {cupOne, cupTwo};
System.out.println("Total Cost is: " +
Starbucks.getTotalCost(cups));
System.out.println(Starbucks.getMessage());
}
}
Cafe.java
public class Cafe {
private double totalCost;
private String message;
public Cafe() {
}
public double getTotalCost(CoffeeCup c[]) {
for(CoffeeCup c1: c) {
totalCost+=c1.getPrice();
}
message="Thank you for visiting Starbucks";
return totalCost;
}
public String getMessage() {
return message;
}
}
CoffeeCup.java
public class CoffeeCup {
private double price;
private String size;
public CoffeeCup(double p , String s) {
this.size=s;
this.price=p;
}
public double getPrice() {
return price;
}
public String getSize() {
return size;
}
}
