    Default Inputs not being applied.

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

       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);
          }
       }

     
        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.

    Default Re: Inputs not being applied.

    I can run your program and CoffeeCup class is being called from CoffeeCup_Driver.

    So you have to check where you are wrong. And if my help is needed then tell me the output you needed.
