Write a Temperature class that will hold a temperature in Fahrenheit, and will provide methods to get and display the temperature in Fahrenheit, Celsius, and Kelvin. The Temperature class should have the following instance variable: ftemp - A double that holds a Fahrenheit temperature. The Temperature class should have the following methods: ReadInput - Uses a Scanner method to populate ftemp with double value. getFahrenheit - Returns the value of the ftemp field, as a Fahrenheit temperature. getCelsius - Returns the value of the ftemp field converted to Celsius. getKelvin - Returns the value of the ftemp field converted to Kelvin. DisplayOutput - The Fahrenheit temperature and the equivalent values in Celsius and Kelvin are gotten and displayed, one per line, and each along with an appropriate message.

See explaination

Explanation:

import java. util. Scanner;

public class TemperatureTest {

public static void main (String[] args) {

Scanner sc = new Scanner (System. in);

System. out. print ("Enter Fahrenheit temperature: ");

double ftemp = sc. nextDouble ();

Temperature temp = new Temperature (ftemp);

System. out. println ("The temperature in Fahrenheit is " + temp. getFahrenheit ());

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

System. out. println ("The temperature in Kelvin is " + temp. getKelvin ());

}

}

class Temperature {

double ftemp;

Temperature (double ftemp) {

this. ftemp = ftemp;

}

double getFahrenheit () {

return ftemp;

}

double getCelsius () {

return ((double) 5/9 * (ftemp-32));

}

double getKelvin () {

return (((double) 5/9 * (ftemp-32)) + 273);

}

}

Output:

$ java TemperatureTest

Enter Fahrenheit temperature: - 40

The temperature in Fahrenheit is - 40.0

The temperature in Celsius is - 40.0

The temperature in Kelvin is 233.0
