See the PrintWriter class for writing text to a file.

Re: Write on File on what is on TextField
I found this very simple application for the PrintWriter.
// Demonstrate PrintWriter import java.io.*; public class PrintWriterDemo { public static void main(String args[]) { PrintWriter pw = new PrintWriter(System.out, true); pw.println("This is a string"); int i = -7; pw.println(i); double d = 4.5e-7; pw.println(d); } }
So I just set the file name on the PrintWriter, but how do I copy the string on the Jtextfield?
Re: Write on File on what is on TextField
Read the API doc for the JTextfield class. It has a method for getting the text it contains as a String.how do I copy the string on the Jtextfield?
