Question

Make a program that (i) asks the user for a temperature in Fahrenheit degrees and reads the number; (ii) computes the corresponding temperature in Celsius degrees; and (iii) prints out the temperature in the Celsius scale.

Answer 1

Answer:

//import the Scanner class to allow for user's input

import java.util.Scanner;

//Create a class declaration with appropriate name

public class FahrenheitToCelsius {

   //Begin the main method where execution starts from

   public static void main(String[] args) {

       //Create an object of the Scanner class to allow reading from standard

       // input

       Scanner input = new Scanner(System.in);

       

       //Prompt the user to enter the temperature

       System.out.println("Enter a temperature in Fahrenheit degrees");

       

       //Read the number and store in a variable of type double

       double fahrenheit = input.nextDouble();

       

       

       //Convert the temperature to Celsius

       double celsius  = (fahrenheit - 32) * (5 / 9.0);

       

       //Print out the result

       System.out.println("The temperature in Celsius is " + celsius);

       

   } //End of main method

   

}   //End of class declaration

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

Sample Output 1:

>> Enter a temperature in Fahrenheit degrees

32

>> The temperature in Celsius is 0.0

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

Sample Output 2:

>> Enter a temperature in Fahrenheit degrees

78

>> The temperature in Celsius is 25.555555555555557
