Class TemperatureReading4

java.lang.Object
  |
  +--TemperatureReading4

public class TemperatureReading4
extends java.lang.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.
