Question

Write a program that convert a temperature in Fahrenheit to the equivalent temperature in Celsius. The initial temperature in Fahrenheit is to be entered at the keyboard. Both temperatures should be output to the screen.

Answer 1

//import the necessary class

import java.util.Scanner;

//Begin class definition

public class ConvertToCelsius{

//Begin main method

public static void main(String []args){

//Create an object of the Scanner class

Scanner input = new Scanner(System.in);

//Display the aim of the program

System.out.println("**Program to convert from Fahrenheit to Celsius**");

//Prompt the user to enter the temperature in Fahrenheit

System.out.println("Please enter temperature in Fahrenheit");

//Receive the user's input

//And store in the appropriate variable

double tempF = input.nextDouble();

//Convert the temperature to Celsius using

//C = (9.0 / 5) * (F - 32)

//C = temperature in Celsius, F = temperature in Fahrenheit

double tempC = (9.0 / 5) * (tempF - 32);

//Display the result

System.out.println("The temperature in degree Celsius is: ");

System.out.println(tempC);

return;

} //End of main method

} //End of class definition

Sample Output

**Program to convert from Fahrenheit to Celsius **

Please enter temperature in Fahrenheit

>> 32

The temperature in degree Celsius is:

0.0
