Read column wise in csv file using java

Question

I have a csv file.I want to read my csv file and store it in a seperate array using java.

ID	Name
1	ramesh
2	rani
3	rahane
4	raja

 

    public static void main(String[] args) throws IOException {
   ArrayList<String> ar = new ArrayList<String>();
 File csvFile = new File("C:\\Desktop\\r2.csv");
         BufferedReader br = new BufferedReader(new FileReader(csvFile));
         String line = "";
         StringTokenizer st = null;
         int lineNumber = 0;
         int tokenNumber = 0;
         while ((line = br.readLine()) != null) {
           lineNumber++;
           //use comma as token separator
           st = new StringTokenizer(line, ",");
           while (st.hasMoreTokens()) {
             tokenNumber++;
              String sd=st.nextToken() + "  ";

             if(sd!=null){
             ar.add(sd);
                 System.err.println(sd);
             }

           }
           tokenNumber = 0;
         }
}

 In this Method all element stores in a single arraylist.
