Is this syntax possible?

for (int counter=o,charArray[0]; counter <=10,charArray[] <=0; counter++, charArray[]++)

I am asking this since I am having a hard time with the code I'm making. I'mplaying around with a string searching code and I want to use that for the following text file with this content:
KA-MA-NA-PA-QA
AA-DA-IA-MA
AA-BA-DA-EA-FA-HA
DA-EA-IA-MA-NA
EA-GA-HA-JA-PA-QA
BA-GA-IA-MA-LA
BA-EA-IA-KA-LA-PA
AA-FA-JA-KA-LA
CA-GA-HA-LA-MA
CA-EA-FA-GA-LA-PA
BA-CA-JA-MA
BA-DA-GA-HA-IA-KA
AA-FA-MA-OA-PA
CA-FA-HA-IA-JA-PA
AA-JA-LA-NA-QA
AA-BA-CA-IA-NA-QA
IA-JA-MA-PA
CA-DA-FA-GA-HA-QA
HA-IA-KA-LA-NA
FA-MA-OA-PA
EA-GA-LA-OA-QA
BA-EA-GA-IA-QA
AA-HA-IA-MA-PA
CA-DA-KA-OA-PA

What I intended for the source code I made is that it should search through only 12 lines in the file, instead of all 24 lines, for any repeating occurrence of a character. From what I did, the code goes through the entire list 12 times instead of going through 12 lines for one loop only. I believed that only a "for" loop can achieve the action I want - though I don't know where in the code I should place it. By the way, I included the code below:

import java.io.*;
import java.util.*;

public class stringsearch{
	public static void main (String args [])throws IOException {
		Scanner search = new Scanner (new File ("stringtext.txt"));
		
		int counterA=0;
		int counterB=0;
		int counterC=0;
		int counterD=0;
		int counterE=0;
		int counterF=0;
		int counterG=0;
		int counterH=0;
		int counterI=0;
		int counterJ=0;
		int counterK=0;
		int counterL=0;
		int counterM=0;
		int counterN=0;
		int counterO=0;
		int counterP=0;
		int counterQ=0;	
			
		int arrayindex=0;
		
		while (search.hasNextLine())
		     { //while loop starting brace
			  String scanline = search.nextLine();
			  String [] charArray = scanline.split("-");
			  for (int counter=0; counter<=42; counter++)
			     { // for loop starting brace
			      if (charArray[arrayindex].equals("AA"))
			        {  //first main outer if loop starting brace
				     counterA++;
						if (counterA>=3) {
				           				  System.out.println ("AA is very common");
				                  		 } else {
	    				 				 	     System.out.println ("AA is least common");
				                  				}
			        }  //first main outer if loop ending brace
			 else if (charArray[arrayindex].equals("BA"))
			        { //second main outer if loop starting brace
				     counterB++;
						if (cluster_B_counter>=3) {
				           						   System.out.println ("BA is very common");
				                  				  } else {
	    				 								  System.out.println ("BA is very common");
				                  				         }		         
			        } //second main outer if loop ending brace
			     } // for loop ending brace
		     }//while loop ending brace
	}
}

Do you have any suggestions on how I should make the code work the way I want it?
