Question

Modify the program below so it also calculates and displays the amount of money Package A customers would save if they purchased Package B or C, and the amount of money Package B customers would save if they purchased Package C. If there would be no savings, no message should be printed.

import java.util.*;

public class Lab2 {
public static void main (String[] args) {
  
//scanner
Scanner input = new Scanner(System.in);
  
//declarations
int hours;
char pack;
double totalCharges = 0;
  
//inputs
System.out.println("Enter the letter of the package purchased (A, B, or C):");
pack = input.next().charAt(0);
  
System.out.println("Enter the hours worked:");
hours = input.nextInt();
  
//switch Statements
switch (pack) {
case 'A': {
totalCharges = 9.95;
if (hours > 10)
totalCharges += (hours - 10) * 2;
}
break;
case 'B': {
totalCharges = 13.95;
if (hours > 20)
totalCharges += (hours - 10) * 1;
}
break;
case 'C': {
totalCharges = 19.95;
}
break;
default: System.out.println("Incorrect Package...please choose A,B, or C.");
}
  
System.out.printf("The monthly bill on the package " + pack + " is: $%.2f\n", totalCharges);
  
}
}
