(Conversions between Celsius and Fahrenheit) Write a class that contains the following two methods:

/** Convert from Celsius to Fahrenheit */

public static double celsiusToFahrenheit (double celsius)

/** Convert from Fahrenheit to Celsius */

public static double fahrenheitToCelsius(double fahrenheit)

The formula for the conversion is as follows:

fahrenheit = (9.0 / 5) * celsius + 32

celsius = (5.0 / 9) * (fahrenheit - 32)

Write a test program that invokes these methods to display the following tables:
