An alphanumeric character is one that contains only digits and letters (no punctuation or special characters). It would be good to define a Java type AlphaNumCharacter which would allow: characters to be compared with each other and converted to and from ASCII codes; fixed and variable sized collections of alphanumeric characters; combination with other properties such as "lower case" (no upper case letters) to make a type for Lower AlphaNumCharacter etc. Considering different mechanisms for defining such a type, discuss which of these requirements could be met.
