line number
hiya
i m new in java, i've written a code for file input,its working, but now i need to print the line number, i mean how many line it has printed. i attach the code here.
try
{
fin = new FileInputStream ("c:\\readfile.txt");
DataInputStream in = new DataInputStream(fin);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
while ((strLine = br.readLine()) != null) {
System.out.println (strLine);
}
fin.close();
}

i use catch block for IOException.
this program can read from file line by line, and i need all the line numbers.
Thank you

kazitula

Code:
try { fin = new FileInputStream ("c:\\readfile.txt"); DataInputStream in = new DataInputStream(fin); BufferedReader br = new BufferedReader(new InputStreamReader(in)); String strLine; int lineCount = 0; while ((strLine = br.readLine()) != null) { System.out.println (strLine); lineCount++; } fin.close(); System.out.println("lineCount = " + lineCount); }

Yep, simply use a counter variable there just after writing the line. Check the hardwired code carefully.
