Under discussion

how to give file name on console I am giving like "d:\test.txt" but error is coming

1. Read a file name from the console.
2. Read lines from the console until the user enters the "exit".
3. Write all the entered lines to the file, each on a new line.

Requirements:

The program must read the file name from the console.
Create and use a BufferedWriter object.
The program should not read anything from the file system.
The program must read lines from the console until the user enters "exit".
The program must write absolutely all of the entered lines (including "exit") to the file, each on a new line.
The main method should close the BufferedWriter object after using it.

package com.codegym.task.task13.task1319; import java.io.BufferedReader; import java.io.BufferedWriter; import java.io.FileWriter; import java.io.InputStreamReader; import java.io.IOException; /* Writing to a file from the console */ public class Solution { public static void main(String[] args)throws IOException { // write your code here BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); String s = reader.readLine(); FileWriter writer = new FileWriter(s); BufferedWriter bw = new BufferedWriter(writer); String a=""; while(true){ a=reader.readLine(); if(a.equals("exit")) break; bw.write("\n"); bw.write(a); } bw.write(a); bw.close(); } }

When you break after "exit", and try to write the var a to the file, you are not including a new line. The new line only gets put in if the while loop did not break. Your also adding an newline before writing anything to the file, so the first line of the file will be blank
