There's plenty of tutorials out there on this sort thing but here's a basic set up.

You'll need to import:
java.io.FileWriter
java.io.PrintWriter

Then in your code you want to create these objects:

FileWriter fw = new FileWriter("this_string_is_the_filename");
PrintWriter pw = new PrintWriter(fw);

//now do your writing, for example:
pw.println(textfield.getText());

//After all the output is done, make sure you close the file.
pw.close();

The PrintWriter class just functions like System.out with all the print and println methods you'll ever need.
