String[] names = namesString.split(",");
String[] values = valuesString.split(",");

for(int i=0;i<names.length;i++){
System.out.println(names[i] + "      " + values[i];
}

So what is namesString here, Is that contain first line of text file, If so it is giving me error – niren Sep 24 '13 at 07:03
`String[] names = namesString.split(",");` double quote is working for me – niren Sep 24 '13 at 07:06
Thanks, that will be double quote. – Masudul Sep 24 '13 at 07:10

try {
            File file = new File("D:\\temp\\test.txt");
            InputStreamReader reader = new InputStreamReader(new FileInputStream(file));
            BufferedReader bufferedReader = new BufferedReader(reader);
            String namesString = bufferedReader.readLine();
            String valuesString = bufferedReader.readLine();
            String[] names = namesString.split(",");
            String[] values = valuesString.split(",");
            for (int i = 0; i < names.length; i++) {
                System.out.println(names[i] + "\t" + values[i]);
            }
            bufferedReader.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
