in this coding i tries to read the lines specific with and write on another notepad.this coding works well for english characters.but for tamil if i tries to count it count as:

(e.g)தமிழ்

it counts as 5..(i.e)"த", "ம", "ி", "ழ" and "்".
but i want to count it as 3(i.e)"த", "மி" and "ழ்"

What I have tried:

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileReader;
import java.io.FileWriter;

public class ii {

public static void main(String[] args) {
    FileReader fr = null;
    BufferedReader br =null;
    FileWriter fw=null;
    BufferedWriter bw=null;

    String [] stringArray;
    int counLine = 0;
    int arrayLength ;
 String s="";
   String stringLine="";
 
   try{
        fr = new FileReader("F:\\New folder (2)\\N.txt");
        fw=new FileWriter("F:\\New folder (2)\\o.txt");
        br = new BufferedReader(fr);
        bw=new BufferedWriter(fw);
      while((s = br.readLine()) != null){
            stringLine = stringLine + s;
            stringLine = stringLine + " ";
            counLine ++;  
        }
        stringArray = stringLine.split(" ");
        arrayLength = stringArray.length;
    for (int i = 0; i < arrayLength; i++) {
            int c = 1 ;
            for (int j = i+1; j < arrayLength; j++) {
                if(stringArray[i].equalsIgnoreCase(stringArray[j])){
                   c++;
                   for (int j2 = j; j2 < arrayLength; j2++) 
                      {
                       }}
             int k;
              for(k=2;k==stringArray[i].length();i++)
              {
              bw.write(stringArray[i]);
               bw.newLine();
              
              }}} fr.close();
        br.close();
        bw.flush();
            bw.close();
    }catch (Exception e) {
        e.printStackTrace();
    }}}

Your problem comes from the fact that some chars are compound of more than 1 char.
Some chars have sufix
aka "மி" is compound of a leading char "ம" and a suffix char "ி".

I don't know your alphabet, but rather than reading chars 1 by 1 like with Latin alphabet, you have to detect if a char have a suffix or not.
Either you need a list of all combination of char+suffix, either you have to check if actual char is followed by a suffix char.

In any case you need to change your code to handle the situation.

yes i have possible letters in a string

String s = "ஃஅஆஇஈஉஊஎஏஐஒஓஔக்ககாகிகீகுகூகெகேகைகொகோகௌங்ஙஙாஙிஙீஙுஙூஙெஙேஙைஙொஙோஙௌச்சசாசிசீசுசூசெசேசைசொசோசௌஞ்ஞஞாஞிஞீஞுஞூஞெஞேஞைஞொஞோஞௌட்டடாடிடீடுடூடெடே";

Then you have to check if actual char and next one are in the string.
