While loop

Question

I am new to Java and need some assistance with the following program:
Write a program that asks for the user's name and then writes that name to the monitor with either "Ms." or "Mr." in front, depending if the name is for a female or male. Assume that the only female names are
* Amy
* Buffy
* Cathy
and that the only male names are
* Elroy
* Fred
* Graham
All other names will be echoed without a title. The program continues looping until the user hits "enter" without first typing a name.
C:\>java Title
Enter a name:
Amy Johnson
Ms. Amy Johnson
Enter a name:
Fred Smith
Mr. Fred Smith
Enter a name:
Zoltan Jones
Zoltan Jones
Enter a name:
C:\>
Hints: Use a Scanner to read user input. Uses a while loop that tests the length of the input line. Use startsWith() to test the names.
Here's what I have so far:
import java.util.*;
public class TitleApplier
      * @param args
     public static void main(String[] args)
          Scanner scan = new Scanner (System.in);
          System.out.println ("Please enter your name:");
          String name = scan.nextLine();
          while (name.startsWith("A"))
               System.out.println ("Ms. ".concat (name));
               if (name.startsWith ("B"))
                    System.out.println ("Ms. ".concat (name));
               if (name.startsWith ("C"))
                    System.out.println ("Ms. ".concat (name));
               if (name.startsWith ("E"))
                    System.out.println ("Mr. ".concat (name));
               if (name.startsWith ("F"))
                    System.out.println ("Mr. ".concat (name));
               if (name.startsWith ("G"))
                    System.out.println ("Mr. ".concat (name));
               else
                    System.out.println (name);
Here are the problems are I am having:
I am asked to use a while loop that tests the length of the input, I am not sure how I would go about doing that.
When I enter Amy the program keeps looping, but it does not do that for any other name.
When I enter any of the other names, I get two outputs one with a title and one right below that with out the title. Is there a way to get one output, the one with the title?

if() {
  //what ever
  else if() {
    //what ever
  else if() {
    //what ever
  }
