# How to append text to an existing file in Java

I need to append [text](https://www.mindstick.com/blog/301635/did-people-reinvent-texting-to-express-the-full-range-of-emotions) repeatedly to an existing [file](https://www.mindstick.com/articles/59/encrypting-and-decrypting-files-using-c-sharp) in Java. How do I do that?

You can use fileWriter with a true for appending.\

```
try{    String filename= "MyFile.txt";    FileWriter fw = new FileWriter(filename,true); //the true will append the new data    fw.write("add a line\n");//appends the string to the file    fw.close();}catch(IOException ioe){    System.err.println("IOException: " + ioe.getMessage());}
```
