Trouble with filewriter overwriting files instead of appending to the end

Question

OK, I'm having some trouble writing multiple lines to a text file. the program runs, but it won't use new lines each time when I want it run 4 times, the text file should look like: ``` a b c d ``` instead, it looks like: ``` d ``` who knows how to fix this problem? all imports are correctly imported. source(it's been slightly edited, assume everything is properly defined): ``` import java.io.*; public class Compiler { public static void main (String args[]) throws IOException { //there's lots of code here BufferedWriter outStream= new BufferedWriter(new FileWriter("output.txt")); outStream.newLine(); outStream.write(output); outStream.close(); } } ```

Accepted Answer

Make sure that when you create an instance of a `FileWriter`, that you are appending to the end of it. This can be done by using this specific `FileWriter` constructor which takes an additional `boolean` as a second parameter. This `boolean` tells the `FileWriter` to append to the end of the file, rather than overwriting the file.

```
BufferedWriter outStream= new BufferedWriter(new FileWriter("encoded.txt", true));
```
