reading text file column by column each in a different array

I have this text file 

 SFrm  EFrm   SegAScr Phone
    0    36   -158051 SIL
   37   105   -644247 +NONTRANS+
  106   109    -96452 l SIL w b
  110   112   -125055 w l aa i
  113   115   -150550 aa w 7 i
  116   118   -146662 7 aa i i
  119   122    -46757 i 7 d i
  123   126    -58440 d i SIL e
  127   146    -90776 +MUSIC+

  159   174   -251284 f u f i

  207   223   -194024 a 7 SIL e
  224   350   -434997 +NOISE+
  351   353    -28280 SIL
 Total score:    -2802095

I managed to store this whole thing in a string but I need to store it in some arrays where Each column is represented in a different array I know that I can use .split() as a procedure to convert it into array but I won't be able to discard the spaces between columns.

ps: the text file is generic so these numbers and letters are not constants but the form of it is constant (4 columns)

My main problem now is to catch the duplicate vowels when they are at the beginning of any row in the fourth column and do some calculations with the numbers at the same row if someone has easier approach than mine any help would be appreciated :)

I hope this help:

    public static void main(String[] args) throws FileNotFoundException, IOException {

          FileReader inputFile = new FileReader("input");

          //Instantiate the BufferedReader Class
          BufferedReader bufferReader = new BufferedReader(inputFile);

          //Variable to hold the one line data
          String line="";int index=0;

          String[] column1= new String[100];
          String[] column2 = new String[100];
          String[] column3=new String[100];
          String[] column4=new String[100];



          while ((line = bufferReader.readLine()) != null){

              String temp="";int count=1;
              column4[index]="";
              //System.out.println(line);
               StringTokenizer st = new StringTokenizer(line," ");
              //String tokenizer gets the token from each space
               while(st.hasMoreTokens())
                 { 

                   temp = st.nextToken();
                    //System.out.println(temp);
                  If(temp.equals("Total")){
                      break;
                  }

                  if(count==1)
                  {
                 // System.out.println(temp);
                  column1[index] = temp;
                  }
                 if(count==2){
                  column2[index] = temp;
                   }   
                 if(count==3)
                {
                  column3[index] = temp;
                 }
                if(count==4)
                {
                column4[index] += temp;
                }
               if(count<4)
                  count++;
                }


             index++;              
           }

          for(int i=0;i<index-1;i++){
              System.out.println(column1[i]+" "+column2[i]+" "+column3[i]+" "+column4[i]);
          }

       }

I declared four arrays to store the columns from above data as you wanted. I am using stringTokenizer to get each token of string. I got this output when I printed the data from above array:
