The following problem is based on a problem in a number of Java texts, including Gaddiss' Write a Temperature class that will hold a temperature in Fahrenheit and provides methods to get and display the temperature in Fahrenheit, Celsius, and Kelvin. The Temperature class should have the following instance variable: ftemp - A double that holds a Fahrenheit temperature. The Temperature class should have the following methods: ReadInput - Uses a Scanner method to populate ftemp with double value. getFahrenheit - Returns the value of the ftemp field, as a Fahrenheit temperature. getCelsius - Returns the value of the ftemp field converted to Celsius. getKelvin - Returns the value of the ftemp field converted to Kelvin. DisplayOutput - The Fahrenheit temperature and the equivalent values in Celsius and Kelvin are gotten and displayed, one per line, and each along with an appropriate message. Use the following formula to convert the Fahrenheit temperature to Celsius: Celsius = 5.0/9.0 (Fahrenheit - 32) Use the following formula to convert the Fahrenheit temperature to Kelvin: Kelvin = 273 +5.0/9.0 (Fahrenheit - 32) Demonstrate the Temperature class by writing a separate class that includes a main() method. The demo program should create an instance (ie, an object) of the Temperature class, invoke the ReadInput() method on the object invoke the DisplayOutput method on the object
