Within MethodsPractice. java, write a method public static int planParty2(int f, int c, int p) that performs the same calculations as the previous problem, but returns the number of p-packs needed. planParty2 does not need to consider the number of extra cans, and it should not print anything. Here are some example arguments for the planParty2 method and their expected return values:

// class definition of MethodPractice

public class MethodPractice {

   // main method that begin program execution

   public static void main(String args[]) {

       // call to the planParty2 method is done using some parameter

       // and the return value is displayed

     System.out.println("The number of p-packs needed is: " + planParty2(9, 14, 6));

     System.out.println("The number of p-packs needed is: " + planParty2(4, 6, 3));

     System.out.println("The number of p-packs needed is: " + planParty2(4, 6, 4));

   }

   // planParty2 method with 3 parameters and it return an integer

   // the calculation needed to get the required pack is done here

   public static int planParty2(int f, int c, int p){

       // the party owner is added to list of friend

       // and the value is assigned to totalPeople

       int totalPeople = f + 1;

       // the totalPeople times the can drink

       // is assigned to totalDrinkNeeded

       int totalDrinkNeeded = totalPeople * c;

       // number of packs required is declared

       int numberOfPacks;

       // if the totalDrinkNeeded contains exact multiple of a pack

       // we return the numberOfPack by dividing totalDrinkNeeded with p

       if (totalDrinkNeeded % p == 0){

           return numberOfPacks = totalDrinkNeeded / p;

       }

       // else we compute if the totalDrinkNeeded is not a multiple of a pack

       //  first we get the remainder when the totalDrinkNeeded is divided with p

       // then the needed can is computed by subtracting remainder from p

       // the neededCan is added to totalDrinkNeeded, then divided with p

       // and assigned to numberOfPacks

       // numberOfPacks is returned.

       else {

           int remainder = totalDrinkNeeded % p;

           int neededCan = p - remainder;

           numberOfPacks = (totalDrinkNeeded + neededCan) / p;

           return numberOfPacks;

       }

   }

}

Explanation:

Image showing the detailed question is attached.

The program is written in Java and is well commented. A sample image of program output when it is executed is attached.

i don't think so. although it would be nice. i am pretty sure that was an option an update or two ago. i guess they want you to stay 14 forever. haha.
