I can read it line by line but how to continue now?

public static void main(String[] args) {

 try
 {

                //csv file containing data
    String strFile = "BaseballNames1.csv";

                //create BufferedReader to read csv file
    BufferedReader br = new BufferedReader( new FileReader(strFile));
    String strLine = "";
    StringTokenizer st = null;
    int lineNumber = 0;
    int tokenNumber = 0;

                //read comma separated file line by line
    while( (strLine = br.readLine()) != null)
    {
       lineNumber++;

                        //break comma separated line using ","
       st = new StringTokenizer(strLine, ",");

       while(st.hasMoreTokens())
       {
                                //display csv values
          tokenNumber++;
                      /*                                                      

          String name = dis.readUTF();
          String lastName = dis.readUTF();
          int bDay = dis.readInt();
          int bMonth = dis.readInt();
          int bYear = dis.readInt();
          int weight = dis.readInt();
          double height = dis.readDouble();         */          



             System.out.println("tokel line:"+st.nextToken());  




       }

                        //reset token number
       tokenNumber = 0;

    }


 }
    catch(Exception e)
    {
       System.out.println("Exception while reading csv file: " + e);                  
    }
}

Answer 1

I don’t see commas in your input so breaking it on commas should probably be changed to breaking a line on spaces instead. I also see only one large float number where the heading line has five numbers specified. So generally you’re going to need to clarify what’s going in and what needs to come out.

Tell me this isn’t homework.
