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 holds 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 set Fahrenheit 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. Use the following formula to convert to Celsius: Celsius = (5/9) * (Fahrenheit - 32) • getKelvin: Returns the value of the ftemp field converted to Kelvin. Use the following formula to convert to Kelvin: Kelvin = ((5/9) * (Fahrenheit - 32)) + 273 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 the following format (for example, if the temperature in Fahrenheit was -40): The temperature in Fahrenheit is -40.0 The temperature in Celsius is -40.0 The temperature in Kelvin is 233.0
Explanation / Answer
Hi, Please find my implementation.
Please let me know in case of any issue.
########## Temperature.java ###########
public class Temperature {
// instance variable
private double ftemp;
// constructor
public Temperature(double f){
ftemp = f;
}
public void setFahrenheit(double f){
ftemp = f;
}
public double getFahrenheit(){
return ftemp;
}
public double getCelsius(){
return (5.0/9.0)*(ftemp - 32);
}
public double getKelvin(){
return ((5.0/9.0) * (ftemp - 32)) + 273;
}
}
############# TemperatureTest.java #############
public class TemperatureTest {
public static void main(String[] args) {
Temperature temp = new Temperature(-40);
System.out.println("Temperature in fahrenheit: "+temp.getFahrenheit());
System.out.println("Temperature in calcius: "+temp.getCelsius());
System.out.println("Temperature in kelvin: "+temp.getKelvin());
}
}
/*
Sample run:
Temperature in fahrenheit: -40.0
Temperature in calcius: -40.0
Temperature in kelvin: 233.0
*/
