Question

Write a Temperature class that will hold a temperature in Fahrenheit, and provide methods to get the temperature in Fahrenheit, Celsius and Kelvin. The class should have the following field:

• ftemp – A double that hold a Fahrenheit temperature.

The class should have the following methods:

• Constructor – The constructor accepts a Fahrenheit temperature (as a double) and stores it in the ftemp field.
• setFahrenheit – The setFahrenheit method accepts a Fahrenheit temperature (as a double) and stores it in the ftemp field.
• getFahrenheit – Returns the value of the ftemp field, as a Fahrenheit temperature (no conversion required).
• getCelsius – Returns the value of the ftemp field converted to Celsius.
• getKelvin – Returns the value of the ftemp field converted to Kelvin.

Use the following formula to convert the Fahrenheit temperature to Celsius:

Celsius = (5/9) * (Fahrenheit -32)

In order to convert the Fahrenheit temperature to Kelvin, you must first convert it to Celsius, and then add 273. Hint: Use the getCelsius() method inside of the getKelvin() method!

Demonstrate the Temperature class by writing a separate program that asks the user for a Fahrenheit temperature. The program should create an instance of the Temperature class, with the value entered by the user passed to the constructor. The program should then call the object’s methods to display the temperature in Celsius and Kelvin.

Answer: Hey dear student finds the solution of your query, if you have any doubt feel free to ask. Thanks!!

Copy to code: This code has Tempreature class and a double variable,constructor,setter and getters.In main, create object of the Temperature class and call all methods of the class,print both tempreatures.

import java.io.*;
class Temperature //Temperature class
{
   double ftemp; //data member of the class
  
   public Temperature(double tempF) //constructor
   {
       ftemp = tempF;
   }
   public void setFahrenheit(double f) //method to set setFahrenheit
   {
       ftemp = f;
   }
   public double getFahrenheit() //method to return value from ftemp
   {
       return ftemp;
   }
   public double getCelsius() //method to return value as Celsius
   {
       double celsius;
       celsius =(ftemp-32) ;
       celsius = celsius*0.555;
       return celsius;
   }
   public double getKelvin() //method to return value in Kelvin
   {
       double kelvin;
       kelvin = getCelsius(); //call getCelsius()
       kelvin = kelvin+273;
       return kelvin;
   }
}
class Main
{
   public static void main(String[]args)
   {
       double c,k;
       Temperature t = new Temperature(68.52);//create object of the Temperature class
       t.setFahrenheit(78.2);//call setFahrenheit()
       c = t.getCelsius();//call getCelsius()
       k = t.getKelvin();//cll getKelvin()
       System.out.println("Temperature in Celcius: "+c);//print both Temperatures
       System.out.println("Temperature in Kelvin: "+k);
   }
}
