How to make FileUtils appends instead of overwriting text file

Question

I am using the following to write StringBuilder into an existing text file.

FileUtils.writeStringToFile(file, sb.toString(), StandardCharsets.UTF_8);

The problem is that it overwrites the file where I just want to append sb.toString() to the existing content of file. How to workaround this issue?

Answer 1

It has been implemented in 2.1 version of Apache IO. To append string to the file just pass true as an additional parameter in functions:

example:

 FileUtils.writeStringToFile(file, stringBuilder.toString(), true);
