Conversions between inches and centimeters

Write a class that contains the following two method:


/** Converts from inches to centimeters */
public static double inchToCentimeter(double in)

/** Converts from centimeters to inches */
public static double centimeterToInch(double cm)


The formula for the conversion is:

centimeters = 2.54 x inches

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

Inches     Centimeters     Centimeters     Inches

1.0        2.54            5.0             1.96

2.0        5.08            10.0            3.93

...

9.0        22.86           45.0            17.71

10.0       25.4            50.0            19.68
