Condition 4&5 Don't validate

Question about the task

Writing to a file from the console

Java Core, Level 3, Lesson 11

Resolved

The output is correct, it writes content to the file, every String is on a new line, why doesn't the program validate.

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 javax.imageio.IIOException; import java.io.*; /* Writing to a file from the console */ public class Solution { public static void main(String[] args) throws IOException { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); String fileName = reader.readLine(); BufferedWriter bw = null; try { File file = new File(fileName); FileWriter fw = new FileWriter(file); bw = new BufferedWriter(fw); if(!file.exists()){ file.createNewFile(); } while(true){ String a = reader.readLine(); if(!a.equals("exit")) bw.write(a); bw.newLine(); if(a.equals("exit")){ break; } } } catch (Exception e){ } bw.close(); } }

useful

#1 : Requirements say that you even have to write "exit" word to the file. So remove line 34 if statement and add new line after the line 38 check.

while(true){
    String a = reader.readLine();
     bw.write(a);
      if(a.equals("exit")){
          break;
     }
     bw.newLine();
  }

#2 : if it still doesn't pass all the requirements try removing new file constructor(line 22). pass the file name directly as string to the file writer

Thanks! Silly mistake, I just needed to write the exit line to the file before breaking.

while(true){
                String a = reader.readLine();
                if(!a.equals("exit")) {
                    bw.newLine();
                    bw.write(a);
                }

                if(a.equals("exit")){
                    bw.newLine();
                    bw.write(a);
                    break;
                }
