Question

After having done the hand calculation and pseudocode for a program that models inflating a spherical balloon, now implement the task in Java. Remember, first the balloon is inflated to have a certain diameter (which is provided as an input). Then you inflate the balloon so that the diameter grows by an inch, and display the amount the volume has grown. Repeat that step: grow the diameter by another inch and show the growth of the volume.

Complete the following program.

Complete the following file:

Balloon.java

import java.util.Scanner;

public class Balloon
{
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.print("Diameter: ");
double diameter = in.nextDouble();
  
while (diameter >= 0)
{
double growth = growth + diameter;

System.out.printf("Increase: %.0f", );
System.out.println();

System.out.printf("Increase: %.0f",);
System.out.println();
}
}

Explanation / Answer

import java.util.Scanner;
class Balloon
{
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.print("Diameter: ");
double diameter = in.nextDouble();
double growth=1;
  
int c=0;
while (c<10)
{
double vol=diameter*diameter*diameter*3.14/6;
diameter = growth + diameter;
System.out.printf("Increase in diameter: %.0f",growth);
System.out.println("New Diameter "+ diameter);

double growthvol=diameter*diameter*diameter*3.14/6;
  
System.out.printf("Increase in volume: %.0f",growthvol-vol);
System.out.println("New Volume "+growthvol);
c++;
}
}
}

================================================

What you have written code was little bit wrong so i have modified to run for 10 times.
