need help with StringTokenizer

[ros]

Hello,

I need help writing code that converts a given name like into initials
and surname. For example, if a name is Ricky James, it should do R
James and if the name is Henry William James, that should become H W
James.

I have written a method that converts Ricky James to R James and I
have used StringTokenizer, but I need help if the name has 3 or more
tokens, like the second one.

I know I can use StringTokenizer method hasMoreTokens() but I can't
really make out how the logic works.

My try is pasted below:

code:

void myMethod(String name) {

this.name = name;
StringTokenizer str = new StringTokenizer(name, " ");
int numb = str.countTokens();
String first = str.nextToken();
String second = str.nextToken();
System.out.println("The no. of tokens are - " + numb);
System.out.println("The name is - " + first.charAt(0) + "
" + second);

}



Would really appreciate help with this.

check countTokens() every time after you used nextToken() to see if it
returns 1. if it returns 1, you know there is only one token left.

something like this:

StringTokenizer str = new StringTokenizer(name);

while(str.hasMoreTokens()){
if(str.countTokens() > 1)
str.nextToken().charAt(0);
else
str.nextToken();
}

Thanks for the advice ligerdave. That solved my problem.

Really appreciate your help.
