Don't write text into my txt file

Question

With this code I want to read one text file, put all elements into a arraylist and replace the file with the the arraylist contain. But this code don't write into file and I don't know why...

public void delete(String lineToDelete, String nameFile) throws IOException { file = new File(nameFile); fw = new FileWriter(file,false); read = new Scanner(file); while (read.hasNext()) { itemFile.add(read.nextLine()); } for (int i = 0; i < itemFile.size(); i++) { if (itemFile.get(i).equals(lineToDelete)) { itemFile.remove(i); break; } } for (String itemFile1 : itemFile) { fw.write(itemFile1); fw.write(System.lineSeparator()); //new line } }

Does it throw any errors? Have you tried to step through your code, either with a debugger or by print statements? — scrappedcola

Redundant java tags are unnecessary. What about this code requires a specific version? — ChiefTwoPencils

You need to close your scanner before opening your FileWriter, to avoid conflicts on the file.

 ... read.close(); FileWriter fw = new FileWriter(file,false); for (String itemFile1 : itemFile) { fw.write(itemFile1); fw.write(System.lineSeparator()); //new line } fw.close();

I believe theres a typo. In the last for loop you have fwp.write(...) when your variable's name is fw. This could be the problem.
