 ID Name
 1 ramesh
 2 rani
 3 rahane
 4 raja
 
  1.     public static void main(String[] args) throws IOException {  
  2.    ArrayList<String> ar = new ArrayList<String>();    
  3.  File csvFile = new File("C:\\Desktop\\r2.csv");  
  4.          BufferedReader br = new BufferedReader(new FileReader(csvFile));  
  5.          String line = "";  
  6.          StringTokenizer st = null;  
  7.          int lineNumber = 0;   
  8.          int tokenNumber = 0;  
  9.          while ((line = br.readLine()) != null) {  
  10.            lineNumber++;  
  11.            //use comma as token separator  
  12.            st = new StringTokenizer(line, ",");  
  13.            while (st.hasMoreTokens()) {  
  14.              tokenNumber++;  
  15.               String sd=st.nextToken() + "  ";  
  16.                 
  17.              if(sd!=null){  
  18.              ar.add(sd);  
  19.                  System.err.println(sd);  
  20.              }  
  21.                
  22.            }
