Question

Write a method called CalculateShipping that computes and returns the shipping cost of an item for an online store.

The store's shipping policy states that shipping costs 75 cents per item, plus 25 cents for each ounce of product weight. There is an exception for items priced $100.00 or more, for which shipping is free.

So for an item that costs $12.99 and weighs 6 ounces, the shipping cost is computed as $0.75 + 6 * $0.25 = $2.25. For an item that costs $150.00, shipping costs $0.00.

Also write calls to the method that compute the shipping costs for the 2 above examples, placing the results in variables named cheapItem and expensiveItem.

Answer 1

Java code :

class Main{
  
static double calculateShipping(double cost, double weight){
if(cost>=150){
return 0;
}
return (75d+25d*weight)/100d;
}
public static void main(String[] args) {
double cheapItem = calculateShipping(12.99, 6);
double expensiveItem = calculateShipping(150, 10);
System.out.println("Shipping Cost of cheap item is $"+cheapItem);
System.out.println("Shipping Cost of expensive item is $"+expensiveItem);
}
}

OUTPUT :

Output Sample2 (run) X Shipping Cost of cheap item is $2.25 BUILD SUCCESSFUL (total time: 1 second)
