Problem Statement

A user has entered a list of Strings. We must check each String to see if it meets our criteria for a "customer", and either reject the String or recapitalize and respace it to meet our standards.

Our formatting manual states:

A well-formed customer consists of either 2 or 3 parts. The parts are separated by one or more spaces, but there are no leading spaces or trailing spaces. Each part must be a name or an initial, but the last part may not be an initial. An initial is a letter ('a-z' or 'A-'Z') followed by a period ('.') A name is a sequence of two or more letters ('a-z' or 'A'-'Z').

Our standard for recapitalizing a well-formed customer is that each name or initial should start with an uppercase letter and all other letters should be lowercase. Our standard for respacing a well-formed customer is that any extra spaces between parts should be removed leaving exactly one space between adjacent parts.

Create a class NameCheck that contains a method formatList that is given a String[] namelist and that returns a String[] that includes all the well-formed customers, properly recapitalized and respaced. They should appear in the same order as in the original namelist.

Definition

Class:: NameCheck
Method:: formatList
Parameters:: String[]
Returns:: String[]
Method signature:: String[] formatList(String[] namelist)
(be sure your method is public)

Constraints

namelist will contain between 1 and 50 elements inclusive.
Each element of namelist will contain between 1 and 50 characters inclusive.
Each character in each element of namelist will be an ASCII character (32-126).

Examples

```
{"Doug#as good","bArneY R.", "bArneY   Rubble"," Bob Stone", "Bob B. J. Toms","J. Lo"}
```
```
Returns: { "Barney Rubble",  "J. Lo" }
```
"Doug#as good" is not well-formed because Doug#as is not a name or initial. "bArneY R." is not well-formed because it does not end with a name. " Bob Stone" is not well-formed because it starts with a space. "Bob B. J. Toms" is not well-formed because it has 2 names and 2 initials. "bArneY Rubble" is well-formed, being a first name followed by a last name. "J. Lo" is well-formed, being a first initial followed by a last name.

{"Doug G.","GG WALNUT DOUG", "AB. JONES", "A. BOB J.", "Gg DouG", "GG DOUG"}

Returns: { "Gg Walnut Doug",  "Gg Doug",  "Gg Doug" }

{"A BIG Mess", "A. Big Mess.Mess", "ABig","M.MESS"}

Returns: { }
