StringTokenizer problem
 

Re: StringTokenizer problem
 

How bout this?


Tokens.java

import java.io.*; 

import java.util.*;



class Tokens 

{



     public static void main(String[] args)

     {

         int count=0;

         String array[]= new String[100];

          StringTokenizer st = new StringTokenizer("Diablo & generals|RPG|PG|PS2|20","|");

           while (st.hasMoreTokens()) 

           {

         //System.out.println(st.nextToken());

            array[count] =st.nextToken();

            count++;

           }

          System.out.print(array[0]); //change here to see different token

     }

}

Re: StringTokenizer problem
 

String line = "C&C Generals|Real Time Strategy|PG|PS2|20";

String[] tokens = line.split("|");

for (int i=0;i<tokens.length;i++)

     System.out.println(tokens[i]);

Yup.... I'm using the

line.split("|",5)

Found that in the Sun Java forum. I can forget bout StringTokenizer now,
cause the split method is definitely much more cooler...:mrgreen:

And the StringTokenizer is not recommended as of 5.0 I think...:-|

Well...forced to do my project in Java... if it were in Delphi I can finish it with 1/3 of the time I spent using Java.:twisted:

Thanks for the replies guys...really helped:)

>And the StringTokenizer is not recommended...

What is all this hoo-ha, about using split instead of stringTokenizer. Can anyone explain what I should be using and why?

And what of the subsequent link?

Re: StringTokenizer problem
 

It depends on the situation I guess.

For mine it works just fine. No performance drop compared to StringTokenizer, plus it works better... since there's no more need to create an array or arraylist to store the stuff and it ignores the spaces in between data...plus you get to specify how many tokens you want from each line as a second argument. Also you get to save quite a number of lines.

Was having problems with StringTokenizer cause it detects the spaces as delimeters as well though I specified that the delimeter is only "|".

As for the link, I think it's full of crap. Some people just can't switch to something new where they're already comfortable with the old one. Getting memory leaks in Java is quite impossible, cause that's what a garbage collector is for. You should see how memory leaks are like in Delphi...your com doesn't hang but it moves very very very slow till you reboot...if not it'll hang indefinitely. Looping a 100,000,000 times oh my... :cheesy:

Re: StringTokenizer problem
 

That link makes some valid points about initialization costs. I find splitString easier to use though, and it does more than just search for delimiters, its parameter is actually a regular expression. The regex search could possibly slow the parsing down a bit, but I'm not sure by how much or how much it would even take to be noticable.

Re: StringTokenizer problem
 

Split is simple.
It follows the regular expression.
Anyways for the above code there is slight change

String line = "C&C Generals|Real Time Strategy|PG|PS2|20";
String[] tokens = line.split("\\|");
for (int i=0;i<tokens.length;i++)
System.out.println(tokens[i]);
