im trying to write a class that has a method which returns a String[12][2] .
The String should be like this:
String[0][0] = 12
String[0][1] = 321
String[1][0] = 13
String[1][1] = 321321
here is my class
import java.io.*;
public class Reader{
     public Reader (){
     public String[][] readfromFile ()     {     
          int nreg = 12;
          int i=0;
          int j=0;
          int quebra = '\n';
          int ent=0;
          BufferedReader reader;         
          String[][] saida = new String[12][2];
          char[] cod = new char[5];
          char[] cod1 = new char[5];
          try     {     
               FileReader file = new FileReader("test.txt");
               reader = new BufferedReader(file);
               while (i<nreg) {
                    while(ent != ' ') {
                         ent = reader.read();
                            cod[j] = (char) ent;
                         j++;
                    saida[0]=String.valueOf(cod) ;
                    while (ent != quebra) {
                         ent = reader.read();
                         cod1[j] = (char) ent;
                         j++;
                    saida[i][1]=String.valueOf(cod1) ;
               i++;
          catch (IOException ioe)     {                 
               System.out.println ("I/O Exception occurred!");      
     return saida;
Im getting problem with while and dont know how to deal to make my program runs fine.
My static void method is in another class
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.io.*;
public class exe2{
     public static void main(String args[]){
          String[][] saida = new String[12][2];
          try {
               Reader teste = new Reader();
               saida = teste.readfromFile();
          catch(Exception e){
               System.out.print(e.toString());
          for (int i=0;i<12;i++)
               System.out.println(saida[0]);                
Any help is really apreciated

I have modified this class, but i still have problems
import java.io.*;
public class Reader{
     public Reader (){
     public String[][] readfromFile ()     {     
          int nreg = 12;
          int i=0;
          int j=0;
          int quebra = '\n';
          int ent=0;
          BufferedReader reader;         
          String[][] saida = new String[12][2];
          char[] cod = new char[10];
          char[] cod1 = new char[15];
          try     {     
               FileReader file = new FileReader("test.txt");
               reader = new BufferedReader(file);
               while (i<nreg) {
                    j=0;
                    while(ent != ' ') {
                         ent = reader.read();
                            cod[j] = (char) ent;
                         j++;
                    saida[0]=String.valueOf(cod) ;
                    j=0;
                    while (ent != quebra) {
                         ent = reader.read();
                         cod1[j] = (char) ent;
                         j++;
                    saida[i][1]=String.valueOf(cod1) ;
               i++;
          catch (IOException ioe)     {                 
               System.out.println ("I/O Exception occurred!");      
     return saida;
I see that there is a problem with cod1 because when i run this class
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.io.*;
public class exe2{
     public static void main(String args[]){
          String[][] saida = new String[12][2];
          try {
               Reader teste = new Reader();
               saida = teste.readfromFile();
          catch(Exception e){
               System.out.print(e.toString());
          for (int i=0;i<12;i++)
               System.out.println(saida[0]);                
I hava an arrayoutofbound exception 15 and displays null null null ....
any hint?
