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);
   
    }
}
