Question

Note: Plesae put comment and explain how you go about it Thanks.

Create a Temperature class that internally stores a temperature in degrees Kelvin. Create functions named setTempKelvin, setTempFarenheit, and setTemCelcius that an input in the specified scale, converts the temperature to Kelvin, and store the temperature in the class member variable. Also create functions that return and stored temperature in Kelvin, Fahrenheit, or Celsius. Write the main functions to test your class. Use the equations:

Kelvin = Celsius + 273.15

Celsius = (5.0/9) X (Fahrenheit -32.0)

Explanation / Answer

Using the above two equatins we dervie other equation for converting kelvin to celsius etc. See the convertion function the below class

package current;


//Kelvin = Celsius + 273.15

// Celsius = (5.0/9) X (Fahrenheit -32.0)

public class Temperature {
  
   public static void main(String[] args) {
       Temperature tempCl = new Temperature();
       double temp = 273.15;
       tempCl.setTemKelvin(temp);
       System.out.println("Input = "+temp+" Kelvin");
       System.out.println("Kelvin : "+tempCl.getTemKelvin()+" Celsius: "+tempCl.getTemCelcius()+" Farenheit: "+tempCl.getTemFarenheit());
      
       tempCl.setTemCelcius(temp);
       System.out.println("Input = "+temp+" Celsius");
       System.out.println("Kelvin : "+tempCl.getTemKelvin()+" Celsius: "+tempCl.getTemCelcius()+" Farenheit: "+tempCl.getTemFarenheit());
      
       tempCl.setTemFarenheit(temp);
       System.out.println("Input = "+temp+" Farenheit");
       System.out.println("Kelvin : "+tempCl.getTemKelvin()+" Celsius: "+tempCl.getTemCelcius()+" Farenheit: "+tempCl.getTemFarenheit());
