csv - getting alternate column names while reading a line using buffered reader in java? -

i using code read line in csv , column names,but problem getting alternate cloumn names.it skipping first column reading second , skipping third , reading fourth..

bufferedreader br = new bufferedreader(new filereader(csvfile));                string line = "";                stringtokenizer st = null;                 int linenumber = 0;                 int tokennumber = 0;                   //read comma separated file line line                while ((line = br.readline()) != null) {                  linenumber++;                   //use comma token separator                  st = new stringtokenizer(line, ",");                    while (st.hasmoretokens()) {                    //tokennumber++;                    s.add(st.nexttoken());                    //display csv values                    system.out.print(st.nexttoken() + "  ");                   } 

you calling st.nexttoken() twice in while loop. each time, grab next element.

you may want replace stringtokenizer line.split(",") unless have particular need use (such performance).
