Class TemperatureReading4 

java.lang.Object

   +----TemperatureReading4
public class TemperatureReading4
extends Object
This class encapsulates the data from a temperature reading. The details of how a temperature is stored are hidden from the user of objects created from this class. The public interface of this class requires that the scale of a temperature must always be specified. This provides a safe way to store temperature values.

The default constructor.

o TemperatureReading4 
 public TemperatureReading4(double temperature,
                            char scale)
A constructor that specifies the scale for the temperature. Throws an IllegalArgumentException if an improper temperature scale is specified.

Parameters:
temperature - the temperature in either Celsius or Fahrenheit
scale - specifies the scale for temperature, either FAHRENHEIT or CELCIUS

Methods

o getTemperatureC 
 public double getTemperatureC()
Retrieve the temperature value using the Celsius scale.

o getTemperatureF 
 public double getTemperatureF()
Retrieve the temperature value using the Fahrenheit scale.

o getTimeOfReading 
 public Date getTimeOfReading()
Retrieve a reference to the Date object that holds the time of the temperature reading.

o setTemperatureC 
 public void setTemperatureC(double degreesC)
Set the temperature value using the Celsius scale. Throws IllegalArgumentException if the temperature value given is not realistic.

Parameters:
degreesC - new temperature value in degreees Celsius
o setTemperatureF 
 public void setTemperatureF(double degreesF)
Set the temperature value using the Fahrenheit scale. Throws IllegalArgumentException if the temperature value given is not realistic.

Parameters:
degreesF - new temperature value in degreees Fahrenheit
o setTimeOfReading 
 public void setTimeOfReading(Date newDate)
Set the Date object that holds the time of the temperature reading.

Parameters:
newDate - a reference to a Date object
o toString 
 public String toString()
Overrides:
toString in class Object
o convertCtoF 
 public static double convertCtoF(double degreesC)
A static method that converts numbers from a Celsius value to a Fahrenheit value.

Parameters:
degreesC - a number that is interpreted as a temperature in degrees Celsius
o convertFtoC 
 public static double convertFtoC(double degreesF)
A static method that converts numbers from a Fahrenheit value to a Celsius value.

Parameters:
degreesF - a number that is interpreted as a temperature in degrees Fahrenheit
