Names

When names are recorded in a computer, they are sometimes written with the first name first, like ``Allen Downey,'' and sometimes with the last name first and a comma, like ``Downey, Allen.''

In order to compare names and put them in alphabetical order, it is necessary to convert them into a common form.

1.

Create a new project (no graphics) named Name.

2.

Write a method called hasComma that takes a name as an argument and that returns a boolean indicating whether it contains a comma. If it does, you can assume that it is in last name first format.

3.

Write a method called convertName that takes a name as an argument. It should check whether it contains a comma. If it does, it should just return the string.

If not, then it should assume that the name is in first name first format, and it should return a new string that contains the name converted to last name first format.
