How to export 2D Array to a FIle

I need to write to the any file type ( .txt, .csv) the results obtained @ the marked place with UPPER CASE.
I am dealing with 2D array here.
could any one help me.

package associator;
 
 
import java.io.BufferedReader;
import java.io.DataInputStream;
import java.io.FileInputStream;
import java.io.InputStreamReader;
 
public class Test2Darray {
    private int[][] year2006;
 
 
    
    Test2Darray()
            
    {
            year2006 = new int[52][2];
        
    }
 
     private void loadData()
     {
 
        try {
            FileInputStream fstream = new FileInputStream("E:\\missing\\java\\associator\\321236.ixf");
            DataInputStream in = new DataInputStream(fstream);
            BufferedReader br = new BufferedReader(new InputStreamReader(in));
            String strLine;
 
            int j = 0;
            strLine = br.readLine();
            while (strLine != null) {
 
                String[] starwords = strLine.split("[ \\.,]+");
                for (int i = 1; i < starwords.length; i++) {
                    year2006[j][i - 1] = Integer.parseInt(starwords[i]);
                }
                j++;
                strLine = br.readLine();
            }
            AddMissingValues addMissingValues=new AddMissingValues ();
            year2006 = addMissingValues.GetMissingValues2008(year2006);
 
  WRITE TO THE FILE
 
            for(int[] i:year2006)
                    for(int k:i){
                      System.out.print(k+" ");}
 
                   
 
           
        } catch (Exception e) {//Catch exception if any
            e.printStackTrace();
        }
 
     }
 
    public static void main(String[] args) {
 
          Test2Darray arrayload= new Test2Darray();
            arrayload.loadData();
     }
}

What have you tried? You know how to read a file, is writing to a file that much harder?

use FileOutputStream to write your data to file
