I am want to delete the first line of text file using RandomAccessFile class.
My Input file "bulkwfids.txt"
has the data as below:
234567
345578
455678
566667
Expected output needs to be(first line deleted):
345578
455678
566667
But the actual ouput I am getting is as follows:
78
56
345578
455678
566667
Could someone please clear the doubt.
Here is the code snippet I have written:
import java.io.*;
class DeleteLine
{
public static void main(String [] args) throws FileNotFoundException, IOException
{
RandomAccessFile raf = new RandomAccessFile("C://Users/hp/Desktop/bulkwfids.txt", "rw");
raf.readLine();
int n=0;
for(int i=0;i<3;i++)
{
byte [] buff = new byte[100];
raf.read(buff);
raf.seek(0);
raf.write(buff,n,6);
n=n+6;
raf.readLine();
}
raf.close();
}
}
