Parsing CSV data: Its a simple file with values separated by coma(“,”) or pipe(“|”). It can be with .txt or .csv as the extension of the file. If the file is with .txt you can just read the file as normal. Even .csv is a plain text file with coma separated values, some times it may show junk values.
For this you just convert the file name as filename.txt
Here is the code for that.
File file = new File(“csvFile.txt”);
FileInputStream fileStream = new FileInputStream(file);
InputStreamReader inputStream = new InputStreamReader(fileStream);
BufferedReader buffer = new BufferedReader(inputStream);
String line = “”;
while ((line = buffer.readLine()) != null) {
StringTokenizer token = new StringTokenizer(line, “,”);
ProductDataFeeding dataFeeding = new ProductDataFeeding();
while (token.hasMoreTokens()) {
System.out.println(“value====” + token.nextToken());
}
}
If the file is .csv
File file = new File(“csvFile.csv”);
file.renameTo(new File(“textFile.txt”));
and the remaining code is same.
