Question

For a uni assignment, I have to take input from a text file and sort it into two separate arrays. The text file is a football league table, arranged as such:
Barcelona 34
Real Madrid 32

I have written a piece of code like this:

holdingString = fileInput.readLine ();                
StringTokenizer sort = new StringTokenizer (holdingString + " "); 
countOfTokens = sort.countTokens();
System.out.println (countOfTokens + " tokens: " + holdingString);

This prints out the number of tokens and what the tokens are for each line, so it gives output of
Two tokens: Barcelona 34
Three tokens: Real Madrid 32

I’ve then written this piece of code:

for (int i = 0; i < countOfTokens; i++)
 {
  String temp = sort.nextToken ();          
  System.out.println(temp);
 }

This reads just the next token and prints it out.
However, rather than printing the next token out, I want to check if it is a word or a number, and separate it into a different array accordingly, so it will be like this:
ArrayTeam Zero Element Barcelona
ArrayTeam First Element Real Madrid
ArrayPoints Zero Element 34
ArrayPoints First Element 32

What’s the easiest way to do this? I’ve tried using a try/catch, but didn’t get it right. I’ve also tried using an if statement with \d, but that’s not worked either.

Like AmitD, I agree that using split is more appropriate in this case, but if you still like to use a StringTokenizer you do something like:

StringBuilder teamName=new StringBuilder();
for (int i = 0; i < countOfTokens-1; i++)
{
  if (i>0) teamName.append(' ');
  teamName.append(sort.nextToken());          
}
teamNames[k]=teamName.toString(); //add the new team to your teamNames array
points[k]=Integer.parseInt(sort.nextToken()); //if your points array is of int type
