Temperature class that will hold a temperature in Fahrenheit and provide methods to convert to Celsius and kelvin

Question:

Write a Temperature class that will hold a temperature in Fahrenheit and provide methods to convert to Celsius and kelvin.

Code:

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
