Find a line in a file and remove it

Question

I\'m looking for a small code snippet that will find a line in file and remove that line (not content but line) but could not find. So for example I have in a file following

Answer 1

public static void deleteLine(String line, String filePath) {

    File file = new File(filePath);

    File file2 = new File(file.getParent() + "\\temp" + file.getName());
    PrintWriter pw = null;
    Scanner read = null;

    FileInputStream fis = null;
    FileOutputStream fos = null;
    FileChannel src = null;
    FileChannel dest = null;

    try {


        pw = new PrintWriter(file2);
        read = new Scanner(file);

        while (read.hasNextLine()) {

            String currline = read.nextLine();

            if (line.equalsIgnoreCase(currline)) {
                continue;
            } else {
                pw.println(currline);
            }
        }

        pw.flush();

        fis = new FileInputStream(file2);
        src = fis.getChannel();
        fos = new FileOutputStream(file);
        dest = fos.getChannel();

        dest.transferFrom(src, 0, src.size());


    } catch (IOException e) {
        e.printStackTrace();
    } finally {     
        pw.close();
        read.close();

        try {
            fis.close();
            fos.close();
            src.close();
            dest.close();
        } catch (IOException e) {
            e.printStackTrace();
        }

        if (file2.delete()) {
            System.out.println("File is deleted");
        } else {
            System.out.println("Error occured! File: " + file2.getName() + " is not deleted!");
        }
    }

}
