Question

I'm trying to make a program which the user signs up and his information gets output to a file using simple text output?

Here is my whole class..

package malkawi.login;

import java.awt.ComponentOrientation;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
import java.io.FileNotFoundException;
import java.io.PrintWriter;
import java.io.UnsupportedEncodingException;
import java.util.*;

import javax.swing.*;

import malkawi.login.JTextFieldLimit;

     */


    public void outPutInformation() throws FileNotFoundException, UnsupportedEncodingException {
        PrintWriter writer = new PrintWriter(filename+".txt", "UTF-8");
        writer.println(firstname);
        writer.println(middlename);
        writer.println(lastname);

        writer.println(password);
        writer.println(hotmail);
        writer.println(secretcode);
        writer.close();
    }



}

the problem is that it's not outputting anything out. How is it possible to output the file like 2 folder behind

Thank you!

Answer 1

This is not outputting anything because your variables are initialized before entering anything in the text fields. you need to do like this, or directly write textfield values to the file instead if first saving to variables and then writing to file:

public void outPutInformation() throws FileNotFoundException, UnsupportedEncodingException {

    String filename = user1.getText();
    String firstname = fname1.getText();
    String middlename = Mname1.getText();
    String lastname = Lname1.getText();
    String username = user1.getText();
    @SuppressWarnings("deprecation")
    String password = pass1.getText();
    String hotmail = email1.getText();
    String secretcode = scode1.getText();

    PrintWriter writer = new PrintWriter(filename+".txt", "UTF-8");
    writer.println(firstname);
    writer.println(middlename);
    writer.println(lastname);
    writer.println(username);
    writer.println(password);
    writer.println(hotmail);
    writer.println(secretcode);
    writer.close();
}
