BCS2234 25/8/ 2010 Lab

1. (Conversions between Celsius and Fahrenheit) Write a class
that contains the following method:

/** Converts from Celsius to Fahrenheit */
public static double celsiusToFahrenheit(double celsius)

The formula for the conversion is:

fahrenheit = (9.0 / 5) * celsius + 32

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

Celsius    Fahrenheit    
40.0      105.0


2. (Conversions between feet and meters) Write a class that
contains the following  method:

/** Converts from feet to meters */
public static double footToMeter(double foot)

 The formula for the conversion is: 

meter = 0.305 * foot

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

Feet    Meters    
1.0    0.305
