textfile into arrays.

So say I have a text file with lines of text in this structure:

(stats.txt)
ALr94/00291/44/LPFP/1341

Now i want to be able to divide this line, when ever there is a / and add that to an array. Using a Delimiter i guess. So for this line there would be 5 arrays, ALr94 would go into the first array, 00291 would go into the second etc.

any help or references to text that will help me solve this problem would be most appreciated.

the String.split(...) method is what you want to use. Check out the String API for details.

Wow thanks for quick reply. That has got me rolling :D

Or else using regular expressions.

Isn't that kind of like hunting pigeons with an M16 assault rifle? A bit of overkill?

Not much I think. If you are much cleaver on RegEx it's the easiest way. Anyway over thread starter can mess on this if he/she not familiar with before.

after reading the File with a LineNumberReader.....

use a StringTokenizer....via java.util.StringTokenizer...

StringTokenizer token = new StringTokenizer(<string>,<delimiter>,<boolean include delimiter>)

simpler than this?:

Code:

---

      Scanner scanner = new Scanner(new File(STATS_TXT));
      List<String[]> stringArrayList = new ArrayList<String[]>();
      while (scanner.hasNextLine())
      {
        stringArrayList.add(scanner.nextLine().split("/"));
      }
      for (String[] strings : stringArrayList)
      {
        System.out.println(Arrays.toString(strings));
      }

... or not.

Per the StringTokenizer API:

Quote:

---

StringTokenizer is a legacy class that is retained for compatibility reasons although its use is discouraged in new code. It is recommended that anyone seeking this functionality use the split method of String or the java.util.regex package instead.

---

So the folks at Sun are telling us to avoid using StringTokenizer but instead to use either what Eranga or I suggested.

aw tnx...

we were not allowed to use scanners in our class...

i wonder why...

Scanner is part of Java 1.5 and above. Perhaps you are required to be 1.4 compliant.

May be...

Code:

---

        Scanner scanner = new Scanner(new File(STATS_TXT));
        Pattern p = Pattern.compile("[/s]");
        String[] result = null;

        while (scanner.hasNextLine()) {
            result = p.split(scanner.nextLine());
        }
        for (int i=0; i<result.length; i++) {
            System.out.println(result[i]);
        }

---

Yep, that looks decent and simple as my attempt. Thanks!

Yes, it's depends on the way we want to process the task. I mean sometime the way you explain is much easier than RegEx. Point is we have lots of ways to do the same task.

1 sec im confused as to how this code works. Can you just clarify if im getting this processes right.

Quote:

---

while (scanner.hasNextLine())
{
stringArrayList.add(scanner.nextLine().split("/"));

---

This adds the first value of each line to the first array, 2nd value of each line into the 2nd array etc...?
It doesn't split all the values of the first line and then put them into the first array does it?

here is a more detailed explanation. I have a text file with values like this

asdaf/36532/vsg42/52t
3415/fwgytyd/353tbd/dh45yg
3r6eg/e5ge/35gdf/453s

So I want to be able to put all the first values of each line into the first array, and all the second values of each line in the second array etc..separated by the delimiter /.
thankyou

Did you run the code and see. And sis you read the Java doc?

Ya, bit of misses there. I just write down it only for a single line of text, not for multiple lines.

darn i just del it and yo reply.
yeah i know you were editing fubarable's code.
happends to all of us.

edit: let me add it back in then.

Code:

---

        Scanner scanner = new Scanner(new File(STATS_TXT));
        Pattern p = Pattern.compile("[/s]");
        String[] result = null;

        while (scanner.hasNextLine()) {
            result = p.split(scanner.nextLine());
        [B]// } // moved brace[/B]
            for (int i=0; i<result.length; i++) {
                System.out.println(result[i]);
            }
        [B]} // added brace[/B]

ISP messing up, i'll take my leave now.

I'm not clear what you say here. I didn't edit anyone's post in this thread.

i didn't say that. i meant in your code, it looked like you added regex to fubarable's code.

fubarable's code

Code:

---

      Scanner scanner = new Scanner(new File(STATS_TXT));
      List<String[]> stringArrayList = new ArrayList<String[]>();
      *while loop
      *for loop

---

eranga's code

Code:

---

      Scanner scanner = new Scanner(new File(STATS_TXT));
      [B] Pattern p = Pattern.compile("[/s]");[/B]
      *while loop
      *for loop

---

if its not, then my mistake. now lets back to the OP.
