The number of a 5 euro banknote starts with a land code of two letters, followed by 10 digits. for example, the land code ue stands for france. if we replace the letters of the alphabet by their two-digit positions in the alphabet (e. g. ue is replaced by 21 05), we find a number of in total 14 digits. it appears that the obtained number always equals 7 (mod 9). is this code 1-error correcting? if so, why? if not, give an example of a number of a bank note that has one error in it that cannot be corrected.

Pp 4.1 design and implement a class called sphere that contains instance data that represents the sphere’s diameter. define the sphere constructor to accept and initialize the diameter and include getter and setter methods for the diameter. include methods that calculate and return the volume and surface area of the sphere (see pp 3.5 for the formulas). include a tostring method that returns a one-line description of the sphere. create a driver class called multisphere, whose main method instantiates and updates several sphere objects.
