How do I save a String to a text file using Java?

Question

In Java, I have text from a text field in a String variable called \"text\".

How can I save the contents of the \"text\" variable to a file?

Answer 1

Apache Commons IO contains some great methods for doing this, in particular FileUtils contains the following method:

static void writeStringToFile(File file, String data) 

which allows you to write text to a file in one method call:

FileUtils.writeStringToFile(new File("test.txt"), "Hello File");

You might also want to consider specifying the encoding for the file as well.
