need help with logic for simple text-manipulation function

[Rex]

Hi I want to write a method which takes in a string of names
seperated by a whitespace and puts commas at each whitespace the last
name however, should have "and" before it.

Let me explain this with the help of an example:


The original string is: "Toby Grant Michelle Tom" the procedure should
return "Toby, Grant, Michelle and Tom"


Cheers!
Rex

public class Rex{

String text ="Toby Grant Michelle Tom";

System.out.println(pconvert(text));
}

public static String pconvert(String nlist){
String retval = "";

nlist = nlist.trim();
String[] nams = nlist.split("\\s+");
for (int i = 0; i < nams.length; ++i){
String p = i == (nams.length - 2) ? " and " : ", ";
if (i == (nams.length - 1)){
p = "";
}
retval += (nams + p);
}
return retval;
}
