Question

I want to remove a line from my file (specifically the second line)
so I have used another file to copy in it ,but using the following code the second file contain exactly the same text.(My original file .txt and my final file .xml)

public static File fileparse() throws SQLException, FileNotFoundException, IOException {  
    File f=fillfile();//my original file
    dostemp = new DataOutputStream(new FileOutputStream(filetemp));
    int lineremove=1;
    while (f.length()!=0) {
        if (lineremove<2) {
            read = in.readLine();
            dostemp.writeBytes(read);     
            lineremove++;
        }

        if (lineremove==2) {
            lineremove++;
        }

        if (lineremove>2) {
            read = in.readLine();
            dostemp.writeBytes(read); 
        }
    }

    return filetemp;
}

Answer 1

You do not read the line if the lineremove is 2 and also you check if it is greater than 2 after you increased it when it was 2. Do it like this:

int line = 1;
String read = null;
while((read = in.readLine()) != null){
   if(line!=2)
   {
     dostemp.writeBytes(read);     
   } 
   line++;
}
