need help using StringTokenizer

[Ricky James]

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 but I can't really make out how the logic works.

My try is pasted below:

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.

A loop of some kind (for or while) is necessary, which runs from 1 to numb-1.

Go through the StringTokenizer API, where it says that it is deprecated, and you should use String.split() instead. String.split() returns a String[] array, which you may find easier to use.

Thanks for the tip Ulf. I solved the problem using while loop. I am pasting the code below for the benefit of other beginners.

while (str.hasMoreTokens()){
            if(numb > 1){
                System.out.print(str.nextToken().charAt(0) + " ");                
            }
            else{
                String finalToken = str.nextToken();
                System.out.println(finalToken);                        
            }
            numb--;                
        }   

Appreciate your help.

Cheers
Ricky

Thanks for this tip Ritchie. I have solved the problem using StringTokenizer and have pasted the code of the method in the previous method. But as a next step I am gonna use String.split() to learn that.

Really appreciate you took time to reply to my post.
