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

Answer:

//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
