Inputs not being applied.

My code is not applying my input and I can't figure out why. Any help is appreciated.

Code :

   import java.util.Scanner;
 
    public class CoffeeCup_Driver
   {
       public static void main (String[] args)
      {
         String typeofCoffee;
         double height, radius, addCoffee, amount;
         int input;      
         Scanner scan = new Scanner(System.in);
 
      // prompt user for the name of coffee and the height/radius of the cup
 
         System.out.print("Enter the type of Coffee: ");
         typeofCoffee = scan.nextLine();
         System.out.print("Enter the height of coffee cup: ");
         height = scan.nextDouble();
         System.out.print("Enter the radius of coffee cup: ");
         radius = scan.nextDouble();
 
      //create a new coffee cup with the parameters entered
         CoffeeCup cup = new CoffeeCup (typeofCoffee, radius, height); 
      //prints the cup object
         System.out.println(cup);
      //allow the user to enter the amount they want to pour into the cup
         System.out.print("Enter the amount of coffee to pour: ");
         amount = scan.nextDouble();
         cup.addCoffee(amount);
         System.out.println(cup);
 
 
      //allow the user to enter the width of a sugar cube to add
         System.out.print("Enter the width of a sugar cube:");
         input = scan.nextInt();
         System.out.println(cup);
 
 
      //allow the user to enter the amount of coffee they want to drink
         System.out.print("Enter the amount of coffee to drink:");
         amount = scan.nextDouble();
         cup.drinkCoffee(amount);
         System.out.println(cup);
 
      //empty the coffee cup
         cup.emptyCup();
         System.out.println("Emptying Cup...");
 
      //print the cup object
         System.out.println(cup);
      }
   }

Code :

 
    public class CoffeeCup
   {
      private double volofCup,amtofCoffee;
      private String typeofCoffee;
      private String overflow;
      private int emptyCup;
      private double volofCube;
 
       public CoffeeCup(String type, double radius, double height)
      {
         type = typeofCoffee;
         volofCup =Math.PI * Math.pow(radius, 2) * height;
 
      }
 
       public void emptyCup()
      {
         emptyCup = 0;
      }
 
       public boolean addCoffee(double amtofCoffee)
      {
         amtofCoffee += emptyCup;
 
         if(amtofCoffee >= volofCup)
         {
            amtofCoffee = volofCup;
            return true;
         }
         else
            amtofCoffee = amtofCoffee;
         return false;
      }
 
 
 
 
       public boolean addSugarCube(double width)
      {
         volofCube = Math.pow(width, 2);
         volofCube += amtofCoffee;
         if(amtofCoffee > volofCup)
         {
            amtofCoffee = volofCup;
            return true;
         }
         else{
            return false;
         }
      }
       public void drinkCoffee(double drinkCoffee)
      {
         amtofCoffee -= drinkCoffee;
         if(drinkCoffee > amtofCoffee)
            amtofCoffee = 0;
 
         else{
            this.amtofCoffee -= drinkCoffee; 
 
         }
      }
 
       public String toString(){
         String output = "Cup of Decaf Coffee " +  "\n" +
            "Vol. of the Cup is: " + volofCup +" Cubic Centimeters\n" + 
                       "Cup is: " + amtofCoffee +  "% full";
         return output;
      }
 
 
   }

Those are my two programs but It seems like my main is not calling the driver when i try to enter any input. Any help is appreciated.
