Other method thing:
public class Centimeters

}

public void calculateCentimeters( )
{
centimeter = (2.54 * inches);

}

public void print( )
{
	System.out.println("Inches is equal to : " + inches);
	System.out.println("When the number of inches is converted to centimeters it equals : " + centimeter);
