I am using this code to read a line in csv and get the column names,but the problem is I am getting alternate cloumn names.It is skipping the first column reading the second and then skipping the third and reading the fourth..
BufferedReader br = new BufferedReader(new FileReader(csvFile));
String line = "";
StringTokenizer st = null;
int lineNumber = 0;
int tokenNumber = 0;
//read comma separated file line by line
while ((line = br.readLine()) != null) {
lineNumber++;
//use comma as token separator
st = new StringTokenizer(line, ",");
while (st.hasMoreTokens()) {
//tokenNumber++;
s.add(st.nextToken());
//display csv values
System.out.print(st.nextToken() + " ");
}
You are calling st.nextToken() twice in the while loop. Each time, it will grab the next element.
You may want to replace the StringTokenizer with line.split(",") unless you have a particular need to use it (such as performance).
