i have created this java program but need help by making it the userHours limited to only 0 to 720 for all packages. If any number higher than 720, get this display

Invalid input, please enter number of hours between 0 & 720.  

Let’s try again.  
Enter the customer's package (A, B, or C): A

Java Program:

import java.util.*;

class PackageFee {
  
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
      
       final double PACKAGE_A_BASE_PRICE = 9.95;
       final double PACKAGE_B_BASE_PRICE = 12.95;
       final double PACKAGE_C_BASE_PRICE = 19.95;
      
       final int PACKAGE_A_LIMIT_HOURS = 10;
       final int PACKAGE_B_LIMIT_HOURS = 20;
      
       final double PACKAGE_A_EXTRA_FEE = 2;
       final double PACKAGE_B_EXTRA_FEE = 1;
       int userHours;
       int hoursExceeded = 0;
       double extraCharge = 0;
       double totalBill=0;
      
       String userPackage;
      
       //Loop till user enters correct value
       do {
           //Reading customer package
           System.out.println("Enter the customer's package: ");
           userPackage = sc.nextLine();
          
           //Reading number of hours used
           System.out.println("Enter the number of hours used: ");
           userHours = sc.nextInt();
          
           //Validating number of hours used
           if(userHours < 0 || userHours > 720)
           {
               //Printing error message
               System.out.println("Invalid input, please enter number of hours between 0 & 720.\nLet's try again.\n");              
           }
          
           //Ignoring new line
           sc.nextLine();
       }while(userHours < 0 || userHours > 720);
      
       /* Remaining code here */
   }
}
