This Java program will reformat a user's name. There are two cases that have to be handled: the trivial case of a single name, where the name doesn't have to be changed, and the case where the names must be rearranged.
If the user enters only one name, eg, Madonna, or Prince, display that name without changes.
Input: Madonna Output: Madonna
If the name consists of a first and last name separated by a blank, you must transform it. For example,
Input: Michael Maus Output: Maus, Michael
Using the String methods,
transform this string into the last name, comma, first name format.
Some useful string methods are
A programming style that is extremely useful is called iterative programming.
In this style you write a little bit of the program and run it.
For example, start this with a program that does nothing in
After that compiles and runs (and does nothing), add Java statements that read
the input string (but don't do anything with it yet. Continue in this way
with very small steps.
In this problem you will probably want to do the single name case first. When that is running you try the other, which requires an if statement and string methods.
I don't allow more than the maximum score on a problem, however if you do extra work, it can cancel out points that were taken off for other reasons.
Capitalizing the names would be good extra credit for this program. You can easily use the Java functions to change the case to something standard.
Input: mIcHaEl mAuS Output Maus, Michael
You may use JOptionPane.showInputDialog(...), Scanner.nextLine(), or SavitchIn.readLine(). You must read both names together; you can't ask for the first and last names separately.
