Sedikit perubahan (teks biru) telah di buat terhadap terhadap perjalanan permainan ini sebagai mana yang di tunjukkan pada flowchart di bawah. Ubah suai program java di atas.

2. (Count positive and negative numbers and compute the average of numbers) Write
a program that reads an unspecified number of integers, determines how many
positive and negative values have been read, and computes the total and average of
the input values (not counting zeros). Your program ends with the input 0. Display
the average as a floating-point number. Here is a sample run:

BCS2233 OOP : Programming Exercise1

Programming Exercise 1.
(please provide flowchart and java program for each question. You can create flowchart online at https://www.draw.io/)

1. (Calculate body mass index (BMI) ) Write a program that reads a Weight and Height, then calcculate BMI and displays the result . The formula for the BMI is as follows:
BMI = Weight / (Height x Height);

2. (Converting Fahrenheit to Celsius) Write a program that reads a Fahrenheit degree, then converts it to Celsius and displays the result . The formula for the conversion is as follows:
celsius = (5/9) * (fahrenheit - 32)

Hint
In Java, 5 / 9 is 0, so you need to write 5.0 / 9 in the program to obtain the correct result.

3. (Computing the volume of a cylinder) Write a program that reads in the radius and length of a cylinder and computes its volume using the following formulas:

area = radius * radius * pi
volume = area * length

(pi = 3.14)

Solution
Question 1.
import java.util.Scanner;
public class hello1 {

    public static void main(String[] args) {

        Scanner input = new Scanner(System.in);

    // Prompt the user to enter weight in KG
    System.out.print("Enter weight in Kilogram: ");
    double weight = input.nextDouble();

    // Prompt the user to enter height in Meters
    System.out.print("Enter height in Meters: ");
    double height = input.nextDouble();


    // Compute BMI
        double bmi = weight / (height * height);

    // Display result
    System.out.println("Your BMI is " + bmi);

    }
}
